The mesh number and particle size calculation formula of brown corundum

Brown corundum, white corundum mesh number and particle size calculation formula: M sieve diameter (μm)≈14832.4/ sieve mesh number
Unit size refers to the size of the raw material particles, generally expressed by the maximum length of the particles. The mesh is the size of the screen size of the standard screen. In the Taylor standard screen, the so-called mesh is the number of sieve holes in the 2.54 cm (1 inch) length, and is referred to as the mesh.
The larger the mesh, the finer the particle. Similar to the magnification of metallographic structures.
A plus or minus sign before the mesh number indicates whether the mesh number can be missed. A negative number indicates the mesh that can leak through the mesh number, that is, the particle size is smaller than the mesh size; The positive number indicates that the mesh number cannot be missed, that is, the particle size is larger than the mesh size. For example, the particles are -100 mesh ~+
