Classification of standard sieves and sieve materials 

standard sieves Classification

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 sample special sieve, metallurgical ore inspection sieve, etc.

Screen material

There are three types, each with different characteristics and application ranges: wire mesh (the most widely used mesh has only square holes from 2.36 mm to 0.02 mm), perforated plate mesh (mainly used for large meshes, with round and square holes ranging from 0.2 to several hundred mm), and electroformed mesh (mainly used in high-precision occasions, so that each mesh is within the average error range). As a professional manufacturer of standard screens, it is necessary to have a tool microscope and a projector. The tool microscope is used to check the accuracy of the mesh, using the arithmetic mean method (the latest method is the normal distribution method).
