Standard sieve is mainly used in various laboratories, laboratories, item screening, screening, grading and other inspection departments to accurately screen and filter the particle size structure of granular and powdery materials, the total amount of liquid solids and the amount of debris. , Inspection. This series of inspection sieve has the advantages of low noise, standard sieve body, sieve, filter sample efficiency, and high precision. It is widely used in scientific research and production in metallurgy, powder, chemical, pharmaceutical, building materials, geology, national defense and other departments. , Quality inspection room.

Divided into: conventional standard sample sieve, chemical special sieve, soil special sieve, stone special sieve, sand special sieve, cement special sieve, asphalt special sieve, coal special sieve, metallurgical mineral screening, etc.

Woven wire mesh: low cost, good flexibility, but relatively low accuracy (large mesh is allowed), the mesh may be deformed, (the accuracy of the mesh can be controlled by reaming and shrinking, and the holes can be fixed by electrochemical methods) Generally, manufacturers with high-precision screen production capacity are required to ensure mass production. The application industry is mostly the diamond industry, especially the export manufacturers require the standard negative difference value, because the foreign countries are half the number, and the basic particles account for more than 90%, such as 230, which is between 75 microns and 63 microns.
