Industrial mill discharge size refers to the fineness of the final powder, usually micron or mesh. The so-called mesh granularity or coarseness of the material generally is defined as 1 inch x 1 inch area (in italics) the number of mesh sieve mesh number, the material through The mesh is defined as the number of mesh: 200 mesh, the material through a 1 inch x 1 inch, 200 mesh sieve. So, the larger the mesh, the finer particle size, the smaller the mesh, indicating that the greater the particle size. Before the mesh plus sign indicates whether the mesh of the mesh can be given a statement. Negative numbers can lose a mesh of the mesh, the particle size is less than the mesh size; positive number indicates the number of eyes can not lose a mesh, particle size greater than the mesh size. For example, particles of -100 mesh to 200 mesh, and means that these particles from 100 the purpose of mesh given a statement rather than from a 200-mesh pass undetected in the screening of the particles of this mesh, the mesh should be large (200 the left screen below) and placed in small mesh (100) (200) mesh sieve is -100 to 200 the purpose of teeth Grains.

Microns, we usually refer to the maximum length of the particle size of powders (particles) such as: special aluminum hydroxide H-WF-100 powder particles of 100 microns about 148 mesh, special aluminum hydroxide H-WF-15 the powder particles 15 microns, about 988 mesh.

According to fineness, industrial milling machine can be divided this way:
① coarse crushed Finished Size: raw material particle size in the range of 40 ~ 1500mm, 5 ~ 50mm
② in the smash: the raw material particle size in the range of 10 ~ 100mm, finished size 5 ~ 10mm
③ slightly crushed: the raw material particle size is within the range of 5 ~ 10 mm, refined grain size below 100μm
④ ultrafine grinding: the raw material particle size of 0.5 ~ 5mm within the finished particle size 10 to 25μm below.
