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.

Laboratory powder testing
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.
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.
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.

Test sieves are often used in laboratory tests, so they are also called laboratory test sieves, standard test sieves, etc. The particle size composition of various powder materials is classified, and it is widely used in the precise screening and particle size detection of particulate materials in the abrasive, geological, metallurgical, pharmacopoeia, chemical building materials and other industries.
