The test screen is divided into ordinary test screen, special processing test screen, consolidated abrasive particle size inspection screen, coated abrasive particle size inspection screen, casting test screen, diamond special test screen inspection screen.
According to the material of the screen surface, the test screen is divided into: metal braided mesh test screen, metal perforated plate test screen, electric forming mesh.
Wire woven mesh test screen adopts the national standard GB/T6003.1-1997 production. Its basic mesh size is 2.36mm-0.038mm, in line with the international standard ISO3310-1:1990 R20/3, R20, R40/3 series, screen material is brass, tin bronze, stainless steel. 2.36um-100um adopts nickel plating processing, which can not only improve the mesh accuracy, but also prevent mesh deformation, strong, wear-resistant and durable.
The metal perforated plate test screen adopts the national standard GB/T6003.2-1997, in line with the international standard ISO3310-2:1990 R20/3, R20, R40/3 series, the screen material is copper, and the use of electrochemical processing.
Electroforming test screen is produced by precision electrochemical method, mesh size range :500-5um, mesh size absolute tolerance 2-3um, suitable for scientific research institutions, diamond is widely used.
The test screen frame, screen cover and screen bottom are made of high quality stainless steel.
Test screen, mainly used for particle size analysis of granular material detection, widely used in abrasive, earth, metallurgy, pharmacopoeia, chemical building materials and other industries of granular material screening detection.
