Sieve Analysis Test

What is the Sieve Analysis Test?

Sieve Analysis Test is mainly used to classify the particle size composition of various powder materials, and is widely used in scientific research and production, laboratories and quality inspection rooms in metallurgy, powder, chemical, pharmaceutical, building materials, geology, national defense and other departments. The categories are divided into: conventional standard sample sieve, chemical special sieve, soil special sieve, stone special sieve, sand special sieve, cement special sample sieve, asphalt special sieve, coal sample special sieve, metallurgical ore inspection sieve, etc.

A set of 37 Sieve Analysis Tests, including 12 wire mesh sieves, mesh size 200μm-300μm, in line with international standard ISO3310-1:1990 and national standard GB/T60031-1997 standard R40/3 series of precision electroforming sieves25 Only, the mesh size is 455μm-41μm, the allowable deviation of the mesh size is ≥139μm±3μm, ≤127μm±2μm, check the sieve frame, sieve cover and sieve bottom, which are made of stainless steel.

What is the objective of sieve analysis test?

The purpose of the Sieve Analysis Test is to determine the percentage of different particle sizes in the material. Perform mechanical or sieve analysis to determine the distribution of coarser, larger size particles and use the hydrometer method to determine the distribution of finer particles.

Features of Sieve Analysis Test

1. Made of 304 stainless steel, wear-resistant and high-temperature resistant;

2. The screen is produced in strict accordance with the GB6003.1-1997 standard and selected by the tool microscope, and the screening is more accurate;

3. The wall thickness is 0.6 mm, and the overall molding is sturdy and durable;

4. The screen mesh and the screen frame are fixed by soldering and will not loosen.

How Sieve Analysis Test works

Sieve Analysis Test uses a vertical vibration motor as the vibration source of the whole machine. The vibration motor drives the upper vibrating disc to vibrate, and then transmits it to the upper screen frame of the vibrating disc through the vibration disc. The materials with the aperture of the screen mesh are sieved to the lower sieve frame, so that only the materials of the same particle size are left in each layer of the test sieve, so as to achieve the separation of different materials and determine the particle size composition of the materials.

Steps to use Sieve Analysis Test

1. Weigh the sample according to the regulations.

2. Sieve the samples according to the size of the sieve holes.

3. When the thickness of the sieve layer on each sieve is greater than the maximum particle size value of the sample, the sieve residue on the sieve should be divided into two parts, and sieved again until the throughput of each sieve per minute is no longer. More than 0.1% of the total sample.

4. When the particle size of the sieved particles is larger than 20.0mm, during the sieving process, it is allowed to move the particles with fingers.

5. Weigh the weight of each sieve, accurate to 0.1% of the total weight of the sample.

6. Compared with the total amount of samples measured before sieving, the difference between the sum of all the sieve remainders on the sieve and the remainder at the bottom of the sieve shall not exceed 1%.

Sieve Analysis Test Results

1. Divide the sieve residue on each sieve by the total amount of samples to calculate the fractional sieve residue percentage of the sieve (accurate to 0.1%);

2. The percentage of sieve residue calculated by each sieve is added to the percentage of sieve residue of each sieve larger than the sieve size, and the cumulative percentage of sieve residue is calculated (accurate to 1%);

3. According to the cumulative sieve percentage of each sieve, evaluate the particle gradation of the sample.
