What is Test Analysis Sieve?

Test Analysis Sieve is a sieve used to determine the size distribution of material particles and separate mixtures. It is mainly used to make mixtures of particles of different sizes pass through the sieve. It is suitable for screening in various industries and testing departments. It is used in chemical industry, geological exploration, powder particles. , Building materials, laboratories, medicines, etc. for particle size analysis, filtration and testing, and play the role of screening, filtering and grading.

What are the types of test analysis sieves?

Classification by material: Stainless steel sieve is the most commonly used material, with the advantages of corrosion resistance, high temperature resistance, high strength, etc., suitable for screening of various materials. Copper sieve has good thermal conductivity and is often used for high temperature screening, but it is easy to oxidize. Nylon sieve has good wear resistance and is suitable for screening of fine particles, but its temperature resistance is poor.

Classification by hole type: round hole test analysis sieve is the most common hole type, with uniform hole diameter and good screening effect. The hole type of square hole test analysis sieve is regular, suitable for screening with special requirements for particle shape. The rectangular hole test analysis sieve is suitable for screening with special requirements for particle aspect ratio.

Classification by aperture: The aperture range of the test analysis sieve is very wide, ranging from tens of microns to several millimeters. You can choose the appropriate sieve according to the particle size range of the measured particles.

3. The Test Analysis Sieve machine is made of 304 stainless steel, which is suitable for the screening of corrosive acid and alkali materials and can guarantee its service life.

4. The screening equipment is a small screening equipment, so its vibration motor is small in size and will not produce large noise pollution during work.

How does Test Analysis Sieve work?

Test Analysis Sieve uses a vertical vibrating motor as the excitation source of the entire motor, drives the upper vibrating plate to vibrate through the vibrating motor, and then transmits it to the screen frame placed on the upper part of the vibrating plate through the vibrating plate, and then the screen frame that needs to detect the mesh size Sieve the material particles smaller than the aperture of the sieve to the lower sieve frame, so that only the same particle size is left in each layer of the inspection sieve, so as to achieve the separation of different particle sizes and determine the particle size composition of the material, so that the sieve The materials in the box can achieve very effective filtering, grading and screening purposes.

Test Analysis Sieve Details Display

Test Analysis Sieve is refined from sieve mesh, sieve frame, sieve cover and sieve bottom.

Sieve: The sieve is the most technical part of the standard sieve. Screens are mainly divided into wire woven meshes (the most widely used meshes are only square holes from 2.36 mm to 0.02 mm), punched plate screens (mainly used in large meshes, with round holes and square holes) The mesh size ranges from 0.2 to hundreds of millimeters), electroforming screen (mainly used in high-precision occasions, and each mesh can be within the average error range), the most commonly used type of screen is stainless steel braided mesh, the cost Lowest, good flexibility.

Screen Frames: Frames are round metal circles that hold the mesh in place, standard frame sizes are 3", 8" and 12". Internationally, 100mm, 200mm and 300mm are standard sizes, and the screen frame can be made of stainless steel or brass.

Screen cover: It can protect the screened material from contamination.

Bottom of the sieve: The material is stretched and formed at one time, never rusting, non-magnetic, with precise fit, no leakage of material or water.

How to do sieve analysis testing?

1. Take a sample of 1000 grams.

2. Arrange the sieve set from top to bottom as 4.75 mm, 2.36 mm, 1.18 mm, 600 micron, 300 micron, 150 micron, 75 micron and Pan.

3. After the sample has been weighed, transfer the sample to a 4.75 mm sieve and close the lid.

4. Put the sieve assembly on the mechanical sieving machine and sieve for five to ten minutes.

5. Remove the assembly from the mechanical shaker and weigh the sample remaining on each sieve while recording it on the observation sheet.

Procedure for test analysis sieve

Test sieve analysis is a traditional and effective method for determining the particle size distribution of a material. The particle size distribution of the particles is obtained by using a series of sieves with different apertures to grade the particles in the sample by size.

1. Sample preparation: Randomly sample the material to be tested to ensure that the sample is representative. If the sample is too large, it needs to be crushed, but be careful to avoid excessive crushing that affects the particle size distribution. The sample should be dry to avoid moisture affecting the screening results.

2. Sieve preparation: Select a suitable sieve group according to the particle size range of the sample. The sieve apertures should be arranged in order from small to large. Make sure the sieve is clean, undamaged, and the screen is tensioned.

3. Sieving process: Spread the prepared sample evenly on the top sieve. Stack the sieves on the sieving machine, start the sieving machine, and vibrate the sieve. The sieving time is determined according to the sample properties and the sieve aperture size.

Stop sieving when there is no longer a significant change in the sieve and the sieve.

5. Result analysis: Draw a particle size distribution curve. According to the calculation results, draw a particle size distribution curve to intuitively display the particle size distribution of the sample. According to the particle size distribution curve, analyze the particle size characteristics of the sample, such as average particle size, median diameter, distribution width, etc.

Advantages of test analysis sieves

1. Special screen design: Test analysis sieves use specially designed screens, such as anti-clogging and anti-adhesion screens, which can reduce the clogging and adhesion of particles in screen holes.

2. Vibration technology: Test analysis sieves usually use vibrating screening machines for screening. Vibration can help particles move in the screen holes, reduce adhesion between the particles.

3. Anti-static treatment: For granular materials that are prone to electrostatic effects, screens made of anti-static materials are used to treat particles to reduce the impact of electrostatic effects.

4. Multi-layer screening: For materials with irregular particle shapes or a wide range of particle sizes, multi-layer screening methods can be used to screen in stages to improve screening accuracy.
