What is sieve test used to determine?

Dry Sieve Test is a test for sieving dry powder, granules, drugs and other substances using sieves of different sizes. This test is usually used for the research and determination of particle size analysis, particle distribution, specific surface area and fluidity of materials. Sieving tests typically use a series of standard sized sieves to sieve material. Specifically, the screening test is mainly used to determine the following aspects:

1. Particle size distribution of the material: Sieving tests can provide data on the particle size distribution of the material, including the specific mass and volume of the material contained in the sieve holes at each level.

2. The thickness of the material: the sieving test can also indicate the thickness of the material, such as coarse particles, medium particles and fine particles.

3. Specific surface area: The sieving test can be used to determine the specific surface area of the material, which refers to the surface area per unit mass or volume of the material.

4. Fluidity of the material: The sieving test can also provide the fluidity data of the material. By measuring the flow of the material on the screen and the average arrival time, the optimal fluidity parameters of the material can be obtained.

Sieve tests can be used to determine particle size in solids or liquids. For smaller particles, the common method is to measure by laser particle size analyzer. Sieving test is a very commonly used method in the fields of materials and medicine, which can improve the quality of products and provide reference for product manufacturing and design.
