What Is a Test Sieve?

Test sieve is also called a standard sieve, a standard test sieve, a laboratory vibrating sieve, a sample sieve, a inspection sieve, a standard analysis sieve, etc. The standard test sieve is a tool for particle size classification and particle size detection of the material particles. It is mainly used for the inspection, filtration and detection of the granular structure of granular and powdery materials, the content of liquid solids and the amount of impurities in various laboratories, laboratories, product screening, screening, grading and other inspection departments.

Test sieve usually consists of screen frame, screen mesh, vibrator and base. Test sieve can select different specifications of screen mesh according to needs to achieve screening of different particle sizes. During use, materials are placed on the screen, and through a vibrator or rotating action, the particles pass or are filtered out according to size. Its precise screening performance and reliability make it an indispensable tool in particle analysis and experimental research.

Benefits of Test Sieve

< span>Stainless steel material

The test sieve frame, sieve cover, and sieve bottom are made of high-quality stainless steel, which will never rust, non-magnetic, and have precise coordination and will not leak materials or water.

High screening accuracy

The sieve mesh is the standard aperture, with high precision, and the sieving particle size can reach 0.025mm~3mm.

High temperature resistance

The screen and the screen frame are connected by welding, which can withstand a high temperature of 400°, and can be used for inorganic and organic solutions.

Good interchangeability

All standard screens have good interchangeability and consistency. The platform does not need to be fixed for operation. Multi-layer screens can be installed, up to 8 layers.

Working Principle of Test Sieve

Test sieve uses the YZU vertical vibration motor as the vibration source of the whole machine. The vibration motor drives the upper vibrating plate to vibrate, and then transmits it through the vibrating plate to the screen frame on the upper part of the vibrating plate. The material particles with the sieve aperture are sieved to the lower screen frame, so that only the same particle size materials are left in each screen frame to achieve the separation of different particle sizes and determine the particle size composition of the material to make the material in the screen frame It can be very effective for filtering, grading and sieving purposes.

Components of Test Sieve

Mesh/Screen: The mesh is the most technical part of a test sieve. The most commonly used type of mesh is stainless steel woven wire mesh. This comes in opening sizes 4" (100mm) to 635 mesh (20um).

For more a more in-depth explanation, refer to our article: How to Pick the Right Woven Wire Mesh (Mesh Count, Wire Diameter, and Micron Rating).

Frame: The frame is the round metal circle that holds the mesh in place. The standard frame sizes in the U.S. are 3 inch, 8 inch, and 12 inch. Internationally, 100mm, 200mm, and 300mm are the standard sizes. Sieve frames can be made of stainless steel or brass.

Skirt: The main function of the skirt is to allow the sieves to be stacked without toppling over.

Application of Test Sieve

test sieve application

Test sieves are widely used in abrasives, geology, metallurgy, pharmacopoeia, laboratories, scientific research institutions and industrial production.

In the laboratory, test sieves are used for screening, classifying and separating granular materials to help researchers analyze particle composition and properties.

In scientific research institutions, test sieves can be used for the research and analysis of granular materials to support scientific experiments and data collection.

In industrial production, test sieves are often used for raw material screening, product quality control and process improvement to ensure the qualification and stability of granular materials during the production process.

Test sieves can also be used in food processing, chemical industry, building materials, medicine and other industries for screening and testing of granular materials to ensure product quality and production efficiency.
