Material properties

Condiments mainly refers to vanilla and spices. Vanilla is a variety of plant leaves. They can be fresh, air-dried or ground. Spices are plant seeds, buds, fruits, flowers, bark and roots. Spice flavor is much stronger than vanilla. In some cases, a plant can be used both for the production of herbs and spices. Some condiments are made from a mixture of spices (eg, paprika) or a mixture of herbs (eg, flavored bags).

It is widely used in the diet, cooking and food processing, it is used to improve the taste of food and has the functions of removing fishy, removing gall, greasy, fragrant and adding freshness. Refers to the food can increase the color, smell, taste, appetite, beneficial to human health auxiliary food. Its main function is to enhance the quality of dishes, to meet the sensory needs of consumers, thereby stimulating appetite and enhance human health.

In a broad sense, condiments include salty, sour, sweeteners, flavorings and flavors, such as salt, soy sauce, vinegar, monosodium glutamate, sugar, star anise, fennel, pepper, mustard all belong to this category.

Screening purposes

Application Overview

1. According to whether it is edible, it can be divided into industrial salt and edible salt;

2. According to the production process, it can be divided into: sea salt, mineral salt and vacuum salt;

3. According to the use, it can be divided into: industrial salt, feed salt, snow melting salt, health salt, pickling salt and edible salt.

Types of salt

Solar salt

Feed salt

Industrial salt

Instant Sea Crystal

Snow-melting salt

Refined salt

Salt process flow

sea ​​salt
It is crystallized in sea water, with a higher iodine content and a lower salt concentration. The production of sea salt in my country generally adopts the solarization method, also called the “spreading method”, which uses coastal beaches, builds dams to open up salt fields, and receives tides. The water is raised, attracting seawater to fill the pond, and becomes brine after evaporation by sunlight.
When the evaporation concentration of the brine reaches 25°, sodium chloride is precipitated, which is salt. The process flow of raw salt produced by the Rizhao method is generally: four major procedures: receiving tide, making brine, crystallizing and collecting salt;

mineral salt

Salt mined from salt mines has a higher mineral content and a higher concentration of salt. As the name suggests, mineral salt is salt mined from salt mines, such as rock salt in the desert, Sichuan salt in Sichuan, and mineral salt mined hundreds of meters underground in Poland. Mineral salt is rich in minerals. Mineral salt has been precipitated underground for thousands of years.
In ancient times, industry was underdeveloped and there was little pollution, so the mineral salt has good purity and few impurities. The following methods are mainly used to refine mineral salt:
brine purification → round (flat) pot frying salt → vacuum Evaporation to make salt → Hot-press evaporation to make salt → Hot-press, vacuum and use method to make salt;

Vacuum salt production

The evaporation process uses brine as raw material to produce coarse salt through four-effect evaporation (evaporation tank), advection feeding, downstream salt discharge, and evaporation and crystallization in an externally heated forced circulation evaporator.
The effluent part of the wood leaves is transferred to the nitrate analysis tank after three-stage preheating. The brine is heated up in the nitrate analysis tank and evaporates to nitrate. The mother liquor flows into the flash tank due to the pressure difference, making full use of the waste heat after steam condensation to allow the condensed water to circulate in the flash tank.
Steam flashes out under the pressure difference.

Salt uses, production processes and screening requirements

Application Overview

Titanium dioxide is also called titanium dioxide. Its chemical formula is: TiO2. It has stable chemical properties and does not react with most substances under normal conditions. Titanium dioxide is widely used.

Titanium dioxide sieving mesh size

Screening mesh size: 40-325 mesh or even finer;
Material characteristics: white crystal or white crystal powder, easy to block the network and absorb moisture.

Titanium dioxide used in cosmetics

Titanium dioxide is also increasingly used in cosmetics. Since titanium dioxide is non-toxic and far superior to lead white, titanium dioxide is used in almost all kinds of fragrance powders to replace lead white and zinc white. Just add 5%-8% titanium dioxide to the fragrance powder to get a white color, making the fragrance smoother, with adhesion, absorption and covering power. In gouache and cold cream, titanium dioxide can reduce the greasy and transparent feeling. Titanium dioxide can also be used in various other fragrances, sunscreens, soap flakes, white soaps and toothpastes.
Cosmetic-grade titanium dioxide is divided into oil-based and water-based titanium dioxide. Because of its stable chemical properties, high refractive index, high opacity, high covering power, good whiteness, and non-toxicity, it is widely used in the field of cosmetics for beauty and whitening effects.

Titanium dioxide used in coatings

Titanium dioxide for coatings is divided into two types: anatase type and rutile type. Anatase titanium dioxide and rutile titanium dioxide have different structures and are used in different places. Anatase type titanium dioxide is used in interior wall coatings because it is easy to powder, while rutile type titanium dioxide is often used in exterior wall coatings because of its aging resistance. They all have a stable crystal lattice and are important white pigments and porcelain glazes. Compared with other white pigments, they have superior whiteness, tinting power, hiding power, weather resistance, heat resistance, and chemical stability, especially no toxicity.

Solution and advantage analysis

Since the selection of vibrating screen should include many factors such as: particle size structure, specific gravity, moisture content, viscosity, temperature, processing capacity, etc., you can choose the following models for screening titanium dioxide:

1.Rotary vibrating screen (small output, high precision)

2.Linear vibrating screen (the output and precision are not as good as the rotary vibrating screen)

3. Ultrasonic vibrating screen can achieve a certain particle size distribution in fine selection, making the particle size uniform and fine. It is used as a colorant in the rubber industry and has the functions of reinforcement, anti-aging and filling. Adding titanium dioxide to white and colored rubber products makes them resistant to sunlight, no cracking, no discoloration, high elongation and acid and alkali resistance when exposed to sunlight. Titanium dioxide for rubber is mainly used in automobile tires, rubber shoes, rubber floors, gloves, sports equipment, etc., and is generally anatase type. However, when used in automobile tire production, a certain amount of rutile products are often added to enhance ozone and ultraviolet resistance.

Application Overview

Copper powder obtained by reduction reaction of copper oxide. Fine reduced copper powder with an average particle size of about 10μm is not easy to prepare high-performance products by injection molding due to its irregular powder shape and high residual oxygen content. This study found that the use of a multi-component binder based on a large amount of backbone polymer can overcome the severe friction between powders caused by the irregular powder shape, and smoothly injection mold this fine reduced copper powder.

During sintering, if the residual oxide in the powder can be effectively reduced before the sintering pores are closed, such as proper insulation at a temperature below 900℃, the sintering density of the injection molded component can reach 95% of the theoretical density. Under this condition, the conductivity of the injection molded component can reach more than 80% of the conductivity of pure copper.

• 2 use equipmentRotary vibrating screen/ultrasonic vibrating screen
• 3 Screening mesh 60~325 mesh
• 4 Screening capacity 100kg~200kg/hour

Material and Application

In addition to certain requirements on the impurity content of tungsten powder, the oxygen content must be controlled within a certain range. The commonly used tungsten powder particle size is generally Fisher’s average particle size of 2 to 10 μm. Tungsten powder is in the shape of polygonal particles. In addition, the specific surface area, bulk density, and shaken density of tungsten powder also vary within a certain range. The properties of tungsten powder have a direct impact on the production of tungsten materials and the quality of tungsten powder metallurgy products, especially the impact of purity and particle size is more obvious. Tungsten powder is classified according to purity and particle size and different uses.

The quality of tungsten powder directly determines the quality and alloy properties of tungsten carbide. Tungsten powder classification can effectively change the properties of the powder, solve the problem of coarse and fine powders, reduce the difference between large particle size, small particle size and average particle size, and produce To produce coarser and more uniform tungsten carbide powder; since the characteristics of tungsten determine that it is not easily broken, moderate crushing is carried out before classification to separate the agglomerated particles in the powder, which can effectively separate the powder and improve uniformity; classification must be strictly and finely adjusted System operating parameters, based on the characteristics of the original powder, need to find the optimal operating process.

Steel shot is a kind of spherical particles which made by special material through a special heat treatment. Steel shot is a common surface treatment material, there is a wide range of steel shots, the raw materials and equipment required are also different for different types of shots. The main features of steel shot are following :

Steel shot is a kind of high quality wear-resistant material, hardness of steel shot is moderate, strong toughness, good impact resistance and long service life. It has a good rebound, clean up fast, low consumption When cleaning the workpiece . Steel shot are used in a wide range of applications, such as castings, forgings, machined parts and heat-treated parts. General manufacturing, shipbuilding, etc. Also need to use steel shot.

First, melt high-quality steel , wool, steel scrap, and then thrown the molten steel into the water which forming by centrifugal plate with high-speed centrifuge, the sharp drop in the surface temperature of the steel shots, which is a quenching. The quenched pellets are dried and reheated to a suitable hardness in the furnace and the temper treated steel pellets are sorted by mechanical screen into different grades according to SAE standard for shot peening equipment.

Screening aim

For size grading, rust removal for the workpiece, the particle size uniformity is high, so blasting steel shot manufacturers need to use the vibrating screen for particle size grading and larger particles removal, so as to ensure the uniformity of steel particle size.

According to customer needs to analysis

1. The first question is to clear the type of steel shot?
Steel shots are divided into: alloy steel shots, cast iron shots, glass shots. The commonly used screening equipment are round and rectangular vibrating sieve, but for steel shots screening, most people choose rectangular vibrating sieve, that is, “linear vibrating sieve”.

2. How to choose vibrating sieve?
This needs steel balls manufacturers to confirm which specification is customers’ demand, if only for grading, the single-layer vibrating sieve can be used; if for grading and removing dust, you need to add a layer, it’s two layers vibrating sieve [three exits], and so on, the more specifications you need to select the appropriate layer. Large particles, big capacity demand generally use linear vibrating sieve;
Smaller particle size, high accuracy screening requirements, small capacity demand generally used S49 series vibrating sieve.

3. Precautions of linear sieve selection:
Linear vibrating sieve is generally divided into: 500mm-800mm-1000mm-1200mm-1500mm different width, according to their capacity from small to large, please consult sales about the details. Length can determine the accuracy, if you want to screen more clean, you have to use the relative length of the linear vibrating sieve!

Application Overview

The vacuum residue of petroleum is cracked and coked by a coking device at 500 to 550°C to produce black solid coke. Its appearance is a black or dark gray honeycomb structure, and the pores in the coke block are mostly oval and interconnected.

Petroleum coke application industry

Low-sulfur, high-quality cooked coke, such as needle coke, is mainly used to manufacture ultra-high-power graphite electrodes and certain special carbon products; in the steelmaking industry, needle coke is an important material for the development of new electric furnace steelmaking technologies.

Medium sulfur, ordinary cooked coke is widely used in aluminum smelting.

High-sulfur, ordinary green coke is used in chemical production, such as manufacturing calcium carbide, silicon carbide, etc., and is also used as fuel for metal casting.

With the rapid development of my country’s cement, electrolytic silver, steel and thermal power industries, the demand for low-sulfur petroleum coke has increased sharply. However, with the increasingly stringent environmental protection policies, the use of high-sulfur petroleum coke has been greatly restricted. Therefore, my country’s petroleum coke market will face a shortage of low-sulfur petroleum coke and a serious surplus of high-sulfur petroleum coke in the future.

It can also be used as fuel, but when used as fuel, a graded impact mill is required for ultrafine pulverization. The coke powder can only be burned after being made into coke powder through the equipment, and the coke powder is used as fuel.

Crushing purpose

Crush 200-300 pieces of petroleum coke to 70-80 pieces to ensure combustion particle size.

Application Overview

Coal has a wide range of uses, which can be summarized into three main uses according to its purpose: thermal coal, coking coal, coal chemical industry coal, mainly including coal for gasification, coal for low-temperature carbonization, coal for hydrogenation and liquefaction, etc.

Thermal coal

(1) Coal for power generation: More than 1/3 of China’s coal is used for power generation, and the average coal consumption for power generation is about 370g/(kW·h) of standard coal. Power plants use the calorific value of coal to convert thermal energy into electrical energy.

(2) Coal consumption for steam locomotives: accounting for about 3% of power coal consumption. The average coal consumption index of steam locomotive boilers is about 100kg/(10,000 tons·km).

(3) Coal used for building materials: accounting for more than 13% of coal used for power, with cement using the largest amount of coal, followed by glass, bricks, tiles, etc.

(4) Coal used in general industrial boilers: In addition to thermal power plants and large heating boilers, general enterprises and industrial boilers for heating have many models, large quantities and scattered, and the coal consumption accounts for about 26% of thermal coal.

(5) Domestic coal: The amount of domestic coal is also large, accounting for about 23% of coal used for fuel.

(6) Thermal coal for metallurgy: Thermal coal for metallurgy is mainly anthracite coal for sintering and blast furnace injection, and its consumption is less than 1% of the amount of thermal coal.

Coking coal

Although China is relatively rich in coal resources, its coking coal resources are relatively small. Coking coal reserves only account for 27.65% of China’s total coal reserves.

Coking coal includes gas coal (accounting for 13.75%), fat coal (accounting for 3.553%), main coking coal (accounting for 5.26%), lean coal (accounting for 4.01%), and other unclassified coal (accounting for 0.55%); non-coking coal Coking coal includes anthracite (10.93%), lean coal (5.55%), weakly caking coal (1.74%),
non-caking coal (13.8%), long-flame coal (12.52%), and lignite (12.76%). %), natural coke (accounting for 0.3%), unclassified coal (accounting for 13.80%) and coal with unclear brand (accounting for 1.06%).

The main use of coking coal is to make coke. Coke is smelted at high temperature from coking coal or mixed coal. Generally, about 1.3 tons of coking coal can be used to make one ton of coke. Coke is mostly used in steelmaking and is the main raw material for steel and other industries. It is known as the “basic food” of the steel industry.

It can also be used as fuel, but when used as fuel, a graded impact mill is required for ultrafine pulverization. The coke powder can only be burned after being made into coke powder through the equipment, and the coke powder is used as fuel.

Coal crushing purpose

The crushed coal has a uniform particle size, generally 8-100mm, which can fully burn coal and ensure emissions meet standards.

Application Overview

Graphite is the most commonly used to serve as the anode material in lithium-ion battery manufacturing due to its relatively low-cost and its energy density. Graphite has great conductive properties and for the most part is readily available.

Graphite screening equipment is also called graphite powder screening machine. The graphite screening machine mainly uses ultrasonic waves as the vibration source, which can expand the output.

Why is graphite used in batteries?

This is the most common choice for transportation for graphite anodes because they cope well with the flow of lithium ions during charging and discharging. 3 main types of graphite are used in the process; natural, synthetic, and spherical graphite. All have their advantages and disadvantages, but regardless they need to be sieved at fine sizes to work for the industry. Sieving graphite for battery materials can be a tricky process due to the varying shape of graphite. Many of the powder requirements call for it to be below 44 microns and traditional screeners do not have the energy to screen graphite at these sizes.

Graphite screening requirement

Soil leaching and remediation process

Multi-stage screening ex-situ soil leaching repair method

1. Feed measurement: The contaminated soil enters the next coarse screening system after feed measurement;

2. Coarse screening: The contaminated soil is sprayed with high-pressure cleaning fluid in the drum mud making machine. After dissociation, moistening and cleaning, the stones are effectively separated from soluble pollutants, coarse sand and fine sand, and then enter the high-frequency vibrating screen. ; Materials with a particle size greater than 10mm slide directly from the upper layer of the high-efficiency vibrating screen into the belt conveyor to complete the discharge of gravel materials; the soil slurry enters the second coarse sand classification screen, and is sprayed with clean water or special eluent to separate 3-10mm The coarse sand is screened out and entered into the belt conveyor or transported out;

3. Fine screening: The slurry of materials with a particle size less than 3mm enters the mud pool buffer, is concentrated by the first-level hydrocyclone, and enters the first-level dehydration screen to complete the discharge of medium-coarse sand; materials with a particle size less than 0.3mm in the slurry under the screen After being concentrated by the second-level hydrocyclone, it enters the second-level dehydration screen to complete the further classification of soil particle size and complete the discharging of soil materials; the mud mixture in the overflow processed by the hydrocyclone group and the underflow of the second-level dehydration screen is Enter the stable integrated equipment for harmless treatment of sewage; at this point, the remediation of contaminated soil by leaching is basically completed.

Application Overview

The powder obtained by crushing and grinding wood has a wide range of uses. It can be used as raw material for mosquito coils, leather, clothing, papermaking, electrical appliances, daily necessities, coatings, cat litter, chemicals, insulation materials, outdoor decoration materials, building materials and other products. It is widely used in chemical industry, building materials, medicine, breeding, food, manufacturing, power generation, and other industries; it can also be made into machine-made charcoal for heating.

Wood flour production process flow

Peeling – slicing – crushing – screening – drying – granulating – packaging

Screening purpose

Purpose of screening: The thickness of the crushed material powder is very different. In order to meet the needs of production and preparation, the coarse and fine mixed powders are separated into coarse powder and fine powder through screening.

Output: 500kg–1 ton

Screening mesh: 20, 40, 60, 80, 100, 120 mesh

Demand analysis

1.  Continuous vibration is required during sieving: when wood flour is in a static state, due to the influence of surface free energy and other factors, it is easy to form wood flour blocks and cannot easily pass through the sieve holes. When vibrating continuously, the balance of various forces is destroyed, and only powder smaller than the sieve hole can pass. However, the vibration speed should be moderate. Too fast or too slow will reduce the screening efficiency.

2.  The bamboo and wood flour sieve should be suitable: according to the required wood flour fineness, correctly select the wood flour sieve with the appropriate screen size.

3.  The powder should be dry: if the moisture content of the powder is too high, the viscosity of the wood powder will increase, which will easily block the sieve holes and affect the sieving efficiency.

4.  The thickness of the powder layer should be moderate: not too much should be added to the wood flour sieve. There should be enough room for the wood flour to move on the sieve in a wide range, which is conducive to sifting, but it should not be too little. Too thin, otherwise it will also affect the screening efficiency.

Recommended solutions

Due to its characteristics, wood flour vibrating screening machines often use rectangular linear vibrating screens in the industry. Because the rectangularlinear vibrating screen has a large output and is easy to change the screen, the additional profit after screening and grading the wood powder is greater. Compared with the three-dimensional vibrating screen machine, the output is much higher. Compared with the drum screening machine, the purchase cost is low, easy to use, and it is not easy to block the network.Linear vibrating screen is a suitable equipment for wood flour industry.

Material and Application

Ceramic powder introduction

The so-called ceramic powder is a powdery substance in which all the raw materials are uniformly mixed and then calcined (also called calcination, pre-synthesis) when preparing the ceramic. The chemical reaction between the raw materials of the ceramic is not carried out in a molten state, but it is achieved by diffusion between atoms (or ions) at a temperature lower than the melting point, that is, a solid phase reaction, so The ceramic powder obtained by calcination (pre-synthesis) is already a pure phase crystalline material.

Production Process

Ceramic powder screening purpose

Screening is the grading of materials using screen mesh having a certain size of aperture or gap. When the powder passes through the screen surface, it is classified into two parts, oversize and lower size product.

Requirements analysis

1.The first question to consider is what are the requirements for powder size in different industries?

a.The civil and hydraulic industry has a particle size range of ≥1cm;

b.Metallurgy, gunpowder, food industry size range from 1cm to 40um;

c.The size of the special ceramic powder industry ranges from 40um to 50nm;

2.What is the flow rate?

The flow rate is also the throughput, the amount of sieve that one set of equipment can complete in an hour. This should be calculated according to the amount of material handling. If the throughput is greater than 10 tons, it is definitely to recommend the linear vibrating screen. If the output is small, the rotary vibrating screen can meet the requirements.

3.Screening based on material analysis:

There are two kinds of sieve method: dry method and wet method. When measuring the particle size distribution, it is generally sieved by dry method; the wet method can prevent very fine particles from adhering to the screen hole to block the sieve hole. If the sample contains more water, especially if the particles are finer, if it is allowed to mix with water, it is better to use the wet method when the particles are more cohesive. In addition, the wet method is not affected by the temperature of the material and the atmospheric humidity, and it also can improve the operating conditions with higher precision than dry screening. Therefore, both wet and dry methods are listed as national standard methods for determining the fineness of cement and raw materials.

Added AD, calcium, biqi factor, etc., it is very suitable for babies during the teething period to exercise their gums and relieve pain and itching. Especially as children get older, they salivate more. Eating something to grind teeth can help digest saliva.

Small steamed bun screening is mainly divided into: raw material screening and finished product screening.

Raw material screening

For raw materials such as potatoes, well-known brands like Want Want Group usually use imported potatoes, and domestically they usually use Beidahuang potatoes. False caking will occur during transportation and storage. In summer, biological insects may also appear due to storage temperature and other reasons. Debris such as packaging threads cannot be avoided during manual unpacking. Therefore, potatoes and other raw materials need to be screened for security inspection before entering the formula.

Screening equipment that protects the health of workers, ensures no loss or waste of materials and improves quality. The equipment is designed according to the height of the human body to minimize labor intensity. The design complies with the requirements of the Health and Safety Implementation Guidelines for manual operation tasks. The protective cover is integrated on the sieve plate and is equipped with a film-coated filter element to directly collect dust, which solves the previous problems of materials flying when manually opening the packaging bag, which is harmful to the health of operators, as well as product loss and waste.

Inspection and safety screening is essential, and there is no need to worry about removing large particles, lint, biological flying insects or other foreign matter in the bagged ingredient industry, especially the pharmaceutical and food industries, dust-free security screening can easily intercept it.

Screening of finished small steamed buns

A lightweight, dismantling and easy-to-clean screening machine specially designed for soft and easily deformed wet granules. It is improved on the commonly used linear wet screening machine. It uses the excitation force of the vibration motor and adjusts the design of the vibration plate to make small steamed buns with raw embryos. It is rolled on the mesh plate without being thrown up. At the same time, it moves forward in a straight line with the excitation force of the screen body. Through the two-layer sieve holes, several specifications of upper and lower sieve objects are produced, and they are discharged from their respective outlets.

Combined with the finished small steamed buns and various punching screens, accurate data can be obtained to ensure that the size of the raw embryo is qualified for puffing.

Material properties

Soy protein isolate is extracted from soybeans through a series of processing steps, and then obtain a near-purified protein. Soy protein isolate contains eight essential amino acids, similar with meat, fish, eggs, milk, belonging to the full price of protein. Research shows that protein is the material basis of life and is one of the three major components of human body. The lack of protein can directly lead to growth retardation, low immunity, loose skin and premature aging.

In the many plant-based proteins, the most nutritious is legume protein (also known as soy protein), and legumes contain no cholesterol, which the characteristic of animal foods don’t have. Soy protein has its drawbacks without any processing: the content of methionine (an essential amino acid) is relatively low. Therefore, whole soybeans have an amino acid score of approximately 0.6-0.7.

However, due to the high protein content of soybeans and the absence of cholesterol, soy protein flour is widely used.

Production process

Leaching process, acid precipitation separation process, the neutralization process, flash evaporation process and drying process, the dried soy protein powder need to carry out the final impurity removal, it can be packaged after sieving pine.

Screening purpose

This screening and impurity removal process is to play a protective role, remove the impurities, caking from the soy protein powder, but also has the role of loose materials to ensure the purity of semi-finished soy protein powder raw materials

Sesame is one of the major oilseed crops in China and has high application value. Its seeds contain up to 55% oil. Since ancient times, China has many colored foods and delicacies made with sesame and sesame oil. It has always been known as the highest in the world. Sesame is an oilseed crop, the oil is called sesame oil, is characterized by mellow smell, with heat can be used.

Screening purpose

Sesame screening is generally about the sand in the sesame or sesame after the scouring in the carbon sieve out. Also, farmers who planted a small area of sesame apart from sesame and sesame seeds would dry the sesame seeds and let the sesame itself out. However, this is clearly not suitable for large-scale farmers planting sesame seeds. The heavy workload does not increase the production cost even more.
How to screen as a large-scale growers? How to carry out a screening work before squeezing oil mill? How to sort out clean sesame seeds? Through the wind selection can blow out small light broken pods, rods, powder from sesame. The wind doesn’t blow out through the vibrating screen to grade, because each screen mesh size is not the same, the sesame mixture can be divided into three levels, the first level is impurities which larger than sesame, like some pods, rods, lumps, the second level is clean sesame, the third level is impurities which smaller than sesame, they are generally broken powder, sand, grass seeds and other impurities.

Material and Application

Sugar is a condiment processed from plants such as sugar cane or beet, and its main ingredient is sucrose. Guangxi, Yunnan, Guangdong, Hainan, Fujian, Taiwan and other provinces, as well as Xinjiang and Northeast China are the main sugar-producing areas in my country. Sugar is an important condiment, which can increase the sweetness and umami of dishes and the color of products. It is the main seasoning raw material for making dishes, especially beet varieties.

Granularity of sugar

There are four grades: Refined, Superior, First Class and Second Class

Coarse Grain:0.800 2.50mm

Large Grain:0.630 1.60mm

Medium Grain:0.450 1.25mm

Fine Grain:0.280 0.800mm

1. The grains are uniform and the grain size should not be less than 80% within the following range.

2. The grains or its aqueous solutions are sweet and have no peculiar smell.

3. Dry and loose, white, shiny, no obvious black spots.

Classification of sugar

A Raw sugar

Using sugar cane and beet to extract sugar juice, after simple filtration, clarification, boiling concentration and center separation to form sugar crystals. Light brown in color. Sometimes a little molasses or water. It is the most important sugar product in international trade. Raw sugar is only used as a raw material for sugar refining and cannot be directly added to food or eaten directly.

B White sugar

Using sugar cane and beet as raw materials (one-step method) or raw sugar (two-step method), through juicing, filtration, impurity removal, clarification (the above steps are not required for raw sugar), vacuum concentration, boiling, de-honey, washing Sugar, obtained after drying. White granulated sugar is the most important variety of edible sugar. In foreign countries, basically 100% of edible sugar is white granulated sugar. In China, white granulated sugar accounts for more than 90% of the total edible sugar. White sugar is divided into refined, superior, first-class, second-class.

C Soft white sugar

as raw materials (beets are also directly produced in Xinjiang and other places), which are recrystallized after dissolving. Soft white sugar is a kind of edible sugar that domestic consumers prefer. Its texture is soft and delicate, with small crystal particles, and about 2.5% invert syrup is sprayed in the production process, so the taste is sweeter than granulated sugar. There are three grades of soft white sugar: refined, premium and first-class.

Screening requirements for white sugar

The screening of white sugar is mainly for impurity removal and classification, and the output is 1-50 tons.

Material and Application

The rubber additive refers to a rubber vulcanization accelerator. The vulcanization of rubber is mainly carried out using sulfur, but the reaction of sulfur with rubber is very slow, so vulcanization accelerators have emerged. The addition of the accelerator to the rubber compound can promote the activation of the vulcanizing agent, thereby accelerating the crosslinking reaction between the vulcanizing agent and the rubber molecule, thereby achieving the effects of shortening the vulcanization time and lowering the vulcanization temperature. The main use of vulcanization accelerators are mainly sulfenamides, thiazoles, thiurams, and some terpenoids, thioureas and dithiocarbamates. Among them, sulfenamides have the best comprehensive performance and are the most widely used.

Rubber additive production process

The raw materials are subjected to condensation-oxidation reaction–washing–drying–screening and removing impurities–finished packaging

Sieving aim

The purpose of screening is to remove impurities, because in the above production process, it is inevitable that there will be residues or other foreign matter on the pipe wall of the equipment entering the material. Therefore, it is necessary to carry out screening and impurity removal in order to ensure the quality of the materials.

Analysis of customer screening

The rubber additives have poor fluidity and are easy to be adsorbed on the screen to block the mesh. The output requirements are still large. It is difficult to meet the requirements of the production system with the general sieve machine. According to the above actual situation, we have developed the centrifugal sifter, as long as the equipment is connected in series in the production system, it is placed between the dryer and the packaging machine, so that the whole system is sealed, dust-free and environmentally friendly, and the wind road is used to solve the problem of blockage and the output is large, saving manpower.

If you are in the auxiliaries industry and still have no choice for screening, please choose Gaofu centrifugal sifter, which will make your products invincible in the market competition!

Refractory generally refers to inorganic non-metallic materials with a refractoriness over 1580 ° C. It includes natural ores and various finished products that have been manufactured according to certain requirements. It has a certain high temperature mechanical properties, good volume stability. It is the necessary materials for all kinds of high temperature equipment .

Screening purpose

The main purpose is classification, the particles and powder is divided into different sizes of particle segments

Refractories production process

Qualified raw material powder → Roll crusher → Vibrating screen → Particle analysis and inspection → Dosing electronic scale → Mixing machine → Particle analysis and inspection → Packaging → Finished product

The problem should be paid attention in refractory material production process design

Vibrating screen is generally arranged in the high-level plant in the crushing plant, its span is generally not less than 8m, and 9m can be allowed if the production is complex with multi-species products. Screening equipment center line and bucket elevator centerline in a straight line, their space should ensure the minimum required size for installed tube between the bucket elevator and screening machine, tube tilt angle is not less than 45 °. In order to improve the screening efficiency, make the material covered the screen surface, it can be set at the board in the sieve inlet

Analysis of customer screening situation.

Refractory raw materials is general stored in the silos for ingredients after crushed, fine grinding and screening, The biggest problem of storing powder in silos is particle segregation. Because the powder particles are generally not a single particle size, they are generally from coarse to fine continuous grain size composition, and only the the different proportions between the size of the various powder and particle size.

When the powder is discharged into the silo, the coarse and fine particles begin to delaminate, the fine powder is concentrated in the central part of the discharge port, and the coarse particles roll to the periphery of the silo. When discharged from the silo, the material in the middle out of the discharge port first, the surrounding material will be down with the material layer , and flow into the middle, and then out from the discharge port to cause particle segregation.

At present, the methods to solve particle segregation in the storage silos of production, there are as following:

1. The powder for multi-level screening, so that the grain size difference smaller in the same silo.
2. increase the feeding port, that is, more mouth feeding.
3. Separate silo.

1.Analysis of feed quantity: 5 tons / hour, one bag of 20 kg per time, then 1: 5 000 kg / 30 minutes / 10 kg / bag / min.
Consider question 1: is it a single feed? If the customer is a person feeding, then 1 minute 8 bags can be finished?
Consider question 2: what is the position of the feeding station if a customer or a person is fed? If the customer does not throw the material from the middle of the screen, the material can not be fully screened, so the site layout must be considered.
2.Analysis of sieve machine structure: if the customer designates the sieve machine as SZS-1200 and the outlet diameter is 200mm, the flow and rest angle of the material should be taken into account; if the flow of the material is not good, The outlet of the diameter 200mm can make the material can not flow out smoothly at the outlet, even if it can sift out so much output, it can not make the material flow smoothly. The material at the bottom can not flow out smoothly and quickly, which will make the conical bucket of the double seismic source called the silo, thus hindering the effect of the vibrating screen of the whole equipment.
3.Properties of the material: dry adipic acid, also known as adipic acid, is colorless and transparent crystal powder, odorless, sour. It has a stimulating effect on the eyes, skin, mucous membrane and upper respiratory tract, so the equipment must be strictly sealed when screening, so if the material is artificially fed, there will be a lot of dust, which will bring harm to the human body. Therefore, whether to consider the use of feeding station.

Plastic introduction

Plastic is a synthetic polymer, which is also commonly known as plastic or resin, and is free to change its form. The material is the monomer materials synthesis or condensation reaction polymerization, from synthetic resins and fillers, plasticizers, stabilizers, lubricants, pigments and other additives.

Composition of plastics

The plastic we usually use is not a pure substance, it is made of many materials.The polymer (or synthetic resin) is the main component of plastic, in addition, in order to improve the performance of the plastic, it needs to add many kinds of auxiliary materials in the polymer, such as filling material, plasticizer, lubricant, stabilizing agent, colorant, etc., to become a good performance plastic.

①Synthetic resin

Synthetic resin is the main ingredient of plastic, its content in plastic is generally 40% to 100%. Due to the large content, and the nature of the resin often determines the properties of the plastic, it is often regarded as a synonym for plastic. For example, polyvinyl chloride resin and polyvinyl chloride plastic, phenolic resin and phenolic plastic confused. In fact, resin and plastic are two different concepts. Resin is an unprocessed virgin polymer that is used not only for plastics, but also for paints, adhesives, and synthetic fibers. In addition to a very small part of the plastic containing 100% of the resin, the vast majority of plastic, in addition to the main component of the resin, but also need to add other substances.

②Filling material

Filling material also known as filling agent, which can improve the strength and heat resistance of plastics, and reduce costs. For example, adding wood powder in phenolic resin can greatly reduce the cost, making phenolic plastic as one of the cheapest plastic, while can significantly improve the mechanical strength. Filling material can be divided into two types of organic filling material and inorganic filling material, the former such as wood flour, rags, paper and various fabric fibers, the latter such as glass fiber, diatomaceous earth, asbestos, carbon black and so on.

③Plasticizer

Plasticizers can increase the plastic plasticity and softness, reduce brittleness, and make plastic easy to process. Plasticizers are generally miscible with the resin, non-toxic, odorless, light, heat-stable high-boiling organic compounds, the most commonly used is phthalates. For example, when producing polyvinyl chloride plastic, soft polyvinyl chloride plastic can be obtained if more plasticizer is added. If no or less plasticizer is added (less than 10%), rigid polyvinyl chloride plastic can be got.

④Stabilizer

In order to prevent the synthetic resin decomposition and destruction by the role of light and heat in the processing and use, to extend the service life, it need to be added the plastic stabilizer. Commonly used stearate, epoxy resin and so on.

⑤Colorant

Colorant can make plastic with various bright and beautiful color.Organic dyes and inorganic pigments are used as colorants.

⑥Lubricants

The purpose of the lubricant is to prevent the plastic from sticking to the metal mold during molding and to make the plastic surface smooth and beautiful. Commonly used lubricants are stearic acid and its calcium and magnesium salts.

⑦Antioxidant

Prevent the plastic in the heating molding or the high temperature oxidation, leaving the plastic yellow, cracked, etc.

In addition to the above additives, the plastic can also be added flame retardants, foaming agents, antistatic agents, etc., to meet different requirements.

Plastic classification

According to different types of plastic use characteristics, usually divided into Universal plastic plastic, engineering plastic and special plastic.

①Universal plastic

Generally refers to the large output, wide use, good moldability and cheap plastic. There are five varieties, namely PE, PP, PVC, PS and ABS. They are all thermoplastics.

②Engineering plastic

Generally refers to withstand some external force, has good mechanical properties and high temperature, low temperature performance, dimensional stability is good, can be used as engineering plastics, such as polyamide, polysulfone and so on.

③Special plastic

Generally refers to a special function, can be used for aviation, aerospace and other special applications. Such as fluoroplastic and silicone with outstanding high temperature, self-lubricating and other special functions, and enhance plastic and foam with high strength, high cushioning and other special properties, these plastics are all belong to the category of specialty plastics.

Plastic screening

①Raw materials screening: For example: PE, PP, PVC, PS, ABS, etc. Because of their qualitatively homogeneous particles in production, their screening purpose is to remove impurities and agglomerates.

②Recycling and Screening of Scrap Plastic: Forming Plastic Products for Recycling, for example: Waste Plastic Pipe, Scrap Plastic Scaffold, Waste plastic bottle, etc. They need to screen after crushing.

③Plastic particles screening: Molded plastic particles for grading, the screening purpose is precision graded;

④Resin slices screening: Screening is more difficult, because the resin chips easily bond, and there will be a long single unqualified material, you can post some material to test and then clear screening needs;

⑤Filling material screening: wood flour, glass fiber, diatomaceous earth, natural mineral powder, carbon black etc;

4. Purpose of screening : simple classification , there is no strict requirement for the size of the screen , and the screen can have upper and lower 2 – purpose deviations;
5. Most of the equipment uses two sieve mesh three outlet, at this time the middle is the finished product, the top coarse material into the second crushing; there is also a part of the use of a layer, the thickness of the finished product or fine part for the finished product;
6. The matters to be paid attention to the equipment: above 60 mesh the use of stamping mesh thick wire mesh screen is the best, because this material is corrosive, submother network customers do not like the product * if the customer is to granular finished product, the middle sieve outlet has 5mm material layer as the best state; * single industry requirements, equipment material carbon steel 304 stainless steel can be, according to the material characteristics 304 best.

Polyacrylamide action

1.Flocculation: PAM can flocculate suspensions through electric neutralization, bridging adsorption and flocculation.
-because of this property, it is often used as a purifying agent to flocculate impurities in the treatment of water and thus to purify them.
2.Adhesion: the ability to bond through mechanical, physical, and chemical action.
-this property is also one of the raw materials for paper, products, and petroleum auxiliaries.
3.Drag reduction: PAM can effectively reduce the friction resistance of the fluid. Adding a small amount of PAM in water can reduce the resistance of 50-80.
– the characteristics of water in the water.
4.Thickening: PAM has thickening effect under both neutral and acid conditions. When PH value is above 10 ℃, PAM is easy to hydrolyze. The thickening will be more obvious when the semi-reticular structure is present.
-the characteristics of thickening and adhesion.

Application of anionic polyacrylamide

Application of cationic polyacrylamide

Cationic polyacrylamide (CPAM) exhibits positive electrical properties in acidic or alkaline media, and its molecular weight is usually lower than that of anionic or Nonionic polyacrylamide (Nonionic polyacrylamide). The properties of cationic polyacrylamide are mainly obtained by charge neutralization. This kind of flocculant has the function of removing turbidity and decolorizing.

In alcohol plants, monosodium glutamate plants, sugar mills, meat factories, beverage factories, printing and dyeing factories, the use of cationic polyacrylamide is several or tens of times higher than that of anionic polyacrylamide, non-ionic polyacrylamide or inorganic salt.Because this kind of wastewater generally has negative charge, cationic polyacrylamide is suitable for high speed centrifuge, belt filter press, plate filter press and other special sludge dewatering machinery.

Good agglomeration, easy to peel off the filter cloth and other characteristics. So the dehydration rate is high, the filter cake contains low liquid, the consumption is low, can greatly reduce the user’s use cost. Can also be used in hydrochloric acid, medium concentration of sulfuric acid and other liquids, separation and purification of suspended substances contained therein.

Therefore, the product is widely used in municipal wastewater treatment plants, breweries, food plants, tanneries, paper mills, petrochemical plants, oil fields, metallurgy, chemical industry and chemical industry. Makeup and other sludge dewatering treatment.

Introduction of calcium hydroxide slurry

01) Production process: calcium carbonate is added to a certain proportion of water reaction → calcium hydroxide slurry.

Note: A temperature of about 70° is generated during the reaction, so the calcium hydroxide slurry can be used for drying;

02) Use of calcium hydroxide slurry: used for SO2 in flue gas generated after de-waste incineration;

Note: When using waste calcination to generate electricity, SO2 gas will be generated in the air when the garbage is incinerated. The calcium hydroxide slurry is directly sprayed in the smoke, which will cause SO2 in the flue gas to react with the calcium hydroxide slurry, produce CaSO3·0.5H2O crystal, thereby purifying the SO2 gas generated by the waste incineration;

Purpose of calcium hydroxide slurry filtration

The purpose of the calcium hydroxide slurry filtration is to prevent solid small particles from clogging the tip during spraying with the tip, so 12 mesh is filtered out with coarse solid particles;

Analysis of customer screening needs

01) Gasket: Use wear-resistant and high-temperature rubber gasket, never leaking liquid;

Because calcium carbonate will produce a temperature of 70-80℃ during the process of reacting with it, the gasket must be high temperature resistant;

02) Structure: upper cover plus spray device;

What is the purpose of the top cover with sprinkler? Is it to clean the screen or to dilute the calcium hydroxide slurry during the screening process? The sprinkler head and the water pressure of different choices are also different, so what is the purpose of confirming the spray? This will provide customers with the right type of sprinkler;

Note:The purpose of the customer’s sprinkler is to clean the screen and prevent the mesh from being blocked; therefore, the customer says that it needs 5 kg of water; We must check each detail when checking the requirements with the customer. Because customers have requirements, there must be a reason, we must conduct an in-depth analysis of each requirement, ask questions, in order to recommend more suitable equipment for customers.

Domestic sewage treatment process

Domestic sewage – add flocculant – enter the vibrating screen machine to filter – put into the 200 mesh filter membrane to filter – put into the activated carbon filter bucket to filter – test the water whether compliance, if compliance can be directly discharged into Hanoi.

Filter purpose

Removal hair, shampoo and some plastic bag things in domestic waste water.

Effective analysis accoring to customer needs

1.The first question to consider is what is the filtering purpose of customer by using vibrating screen machine?
Sewage treatment, the general vibrating screen machine used for primary filtration purposes, the initial impurity removal, so the general selection of the filter mesh is 60 mesh, 80 mesh or 120 mesh, the maximum number of filter mesh is 200 mesh.

2.Feeding material pipe diameter size?
The size of the feed pipe diameter directly determines the size of the vibrating screen selection, if the feed pipe diameter is too large, the liquid flow rate will be too large, the selection is too small will lead to liquid filtration not completely; if the feed pipe diameter is too small, and Screening machine large selection, will lead to a large part of the liquid can not be evenly distributed on the screen surface;
In general, feeding pipe diameter between 50-80mm, the general choice is 600-800mm equipment;
Feeding pipe diameter is 80-150mm, the general choice is 1000-1200mm screen equipment;
Liquid filtration in the selection of the general process can not exceed the maximum 1200mm, so replace the screen and the operation will be more convenient.
3.How much flow rate?
Flow rate is the capacity that a device can filter in an hour. This should be based on the solid content of the filter fluid to calculate, if the solid content is <20%, then the selection can be based on diameter of the feeding pipe; If the solid content> 20%, this depends on the material viscosity (CPU) , The greater the viscosity, the slower the liquid filter on the screen surface, the smaller the viscosity, the faster the liquid filter on the screen surface.

According to the final demand of customers to recommend programs

1. To recommend the final solution to the customer, on the one hand is to consider the mesh of filters, feeding pipe diameter, filter volume, but also consider the customer site requirements. Generally speaking, when you filter domestic waste water , especially in oil fields, the mobility of personnel is relatively high. Therefore, sewage treatment is generally designed on a moving vehicle. Therefore, the external dimensions of the vibrating screen also have special design.
2. This is the customer for oil field workers bathing, because of the nature of the oil field workers, staff mobility, sewage treatment is also on the mobile car, then we must consider the operation of the vibrating screen, convenience and overall height and voltage.

Lead trioxide (chemical formula PB3 O 4), commonly known as red Dan, lead Dan, relative molecular weight 685.60. National Standard No.: 61507 / CAS No.: 1314-41-6. Mainly used as antirust pigment, organic synthetic oxidant, battery powder making. It is a fresh orange powder or block solid, it is insoluble in water, but soluble in hot lye, rare nitric acid, acetic acid, hydrochloric acid. It is a toxic chemical.

Screening purpose

To remove particles and fibrous materials that are not thoroughly crushed; remove large caking impurities.

Production process of lead trioxide

After heating and melting of lead, small lead particles are prepared by ball milling and grinding at about 20 ℃ and then calcined at 300 ℃ and then oxidized at 500 ℃ to produce lead trioxide.

Recommend the scheme according to the needs of the customer

1. Lead trioxide is toxic, inhaled in the body will cause respiratory poisoning, when serious directly threaten personal safety, so in the recommended equipment and equipment layout must consider the sealing of equipment itself and the sealing of the upper and lower pipeline connection;
2. Location of equipment: generally speaking, lead trioxide is transported directly to the sieve through a screw feeder.
3. The material after screening is transported directly to the packaging machine through the airflow conveyor under negative pressure, so if the old line is reformed, the height of the equipment must be considered.
4. Maneuverability of the equipment: because lead trioxide itself is very abrasive, the service life of screening is very short, and the average life span is about 4-7 days. Therefore, the convenience of the ring network and the operability of the workers must be considered in the recommended equipment.

Selection of equipment

Because the output is larger and the sieve occupies less, two models are generally recommended:
1.Type WSA-30-100-304 horizontal airflow screen:
Output of equipment: 3-4 tons per hour

Screening problem: when horizontal airflow screen is selected, stainless steel screen is usually chosen, but the working principle of airflow screen is that 960 r-1100 rpm high speed rotation produces centrifugal force and whirlwind propulsion force, thus forcing the material to jet through the screen. The material that passes through the net has the finished product fine material mouth to exclude, cannot cross the net material, especially the fibrous thing will adhere to the screen because of the static electricity often time, on the one hand affects the material passing the net rate, thus increases the equipment and the screen net load, As a result of the material grinding large, so the screen will appear in 3-4 days of rotten mesh phenomenon.

The following is the status of the use of the on-site cage by the customer:

2.SZS-1500 type 1S-304 double vibration source straight row screen
Output of equipment: 4 tons per hour;

Screening problem: because the screen mesh is replaced frequently, it is generally recommended that the sub-mother mesh frame, but the sub-mother mesh frame is heavy and the mesh holes in the screen mesh are thicker at 14 mesh, so it is more troublesome to replace the mesh frame and screen mesh than the airflow screen.

Material and Application

The pigments are a substance that makes an object color. Pigments are soluble and insoluble, with inorganic and organic differences. Inorganic pigments are generally mineral substances. It has long been known that humans use inorganic pigments to paint and smear the body on colored walls using colored soil and ore. Organic pigments are generally obtained from plants and marine animals such as indigo, garcinia, and purple extracted from shellfish in ancient Rome.

Pigmentproduction process

Crushing–drying–conveying–screening–packaging

Sieving aim

In the air flow drying, air flow grinding, air flow wind selection, air separation and air separation crushed, a matching centrifugal sifter can be added to achieve the purpose of filtering and removing impurities. It is of course also possible to add the centrifugal sifter system separately.

Pigment screening problem

The fineness of powder pigments are important factors affecting its quality and market value. Therefore, in the pigment production process, the screening process is the most important link, but due to the characteristics of large pigment viscosity and easy grouping, the phenomenon of pigment bundling and blocking the mesh during the screening process is particularly serious. At the same time, the use of traditional screening process on-site dust flying, environmental pollution, raw material loss and other issues have also been a major problem in pigment production.

Problems with pigment production

In the process of industrial pigment production, the whole set of production equipment system is tight and the equipment is sophisticated and advanced, but the produced products are directly into the packaging machine, often because the industrial impurities in the products directly affect the product quality, and the customer requests compensation when exporting. How to ensure the quality of the product?

Purchasing and selecting reasonable equipment is the fundamental condition for ensuring the product, so the product must be sieved before packaging. This is the only choice, but the pigments are generally nano-scale fineness, sticky and light, to agglomerate into particles. Sometimes the dust is large, which wastes raw materials and pollutes the environment. A general sieve machine cannot solve the screening problem.

It is a perfect strategy to use the special centrifugal sifter for pigment removal. After the use of Hangzhou Lily Clarian Paint Co., Ltd., Tianjin Organic Chemicals, Jinchuan Group, etc., the effect is very good. “It’s like adding another lung to the system and purifying the foreign material,” one client said. The specific operation method is very simple. A complete centrifugal sifter is added in the air flow drying, air flow grinding, air flow air selection and air separation crushing wind path, then it can achieve the purpose of filtering and removing impurities.

It is of course also possible to add the air flow screen system separately. When you see the impurities in the screen, there are signs, thread ends, agglomerates, foreign matter such as oxidized foreign bodies, screws, hair strands, etc. You can safely say that the quality of our products is absolutely no problem and safe. The company’s product quality is stable.

Introduction of pigment special screening machine system

Gaofu Company has developed and produced a pigment-specific screening machine system for the characteristics of pigments. Because the special screen for pigments adopts vertical loading and air atomization and jetting technology, it solves the problem of large viscosity of the pigment and easy to block the screen; in the airway of airflow drying, airflow milling, airflow selection and air separation, Adding special pigment-specific sieves, the whole screening system adopts negative pressure cycle design, and then adds equipment such as dust collectors, which solves the problem of dust and pollution, eliminates waste of raw materials, and achieves environmental cleanliness and economic value.

Application Overview

After the waste tires are initially crushed and pulverized, they become granular coarse powder. After passing through a small steel mill, the powder ground out can reach a fineness of 60 mesh or 80 mesh. Coarse-grained rubber powder is easy to screen with a linear sieve, but the fine powder ground out by steel mill is not easy to screen because the rubber powder itself is too fine and elastic. If you use a traditional linear sieve, it will easily block the screen. The output of the centrifugal screen is low and the accuracy is not high. Choosing a rubber powder screening machine with large output without centrifugal screen has become a major problem for rubber powder manufacturers.
