Test Sieve

Test sieves are a type of equipment used in physical properties testing and inspection in the supply class of Instruments and Laboratory Equipment. They are specifically designed to separate particles based on their size.

Test sieves consist of a metal frame with a woven wire mesh screen. The mesh size of the sieve determines the size of particles that can pass through it. The most commonly used mesh sizes range from coarse to fine, such as 4 mesh (4 wires per inch) to 400 mesh (400 wires per inch).

To use a test sieve, the sample is placed on top of the sieve, and then it is shaken or vibrated to allow the smaller particles to pass through the mesh while retaining the larger particles on top. The retained particles can then be analyzed or measured separately.

Test sieves are widely used in various industries, including pharmaceuticals, food processing, mining, construction, and environmental testing. They are essential for quality control, research and development, and compliance with industry standards.

When selecting a test sieve, it is important to consider factors such as the required mesh size, the material of the sieve (usually stainless steel or brass), and the overall durability and accuracy of the sieve.

In summary, test sieves are an important tool in physical properties testing and inspection. They allow for the separation and analysis of particles based on their size, making them essential in various industries for quality control and research purposes.
