The finished product size of industrial grinder mill refers to the final powder fineness, generally, use a micron or mesh to say. So-called mesh, refers to the size of materials, generally, the definition is how many nets in 1 inch * 1 inch(the area of italics section is wrong),that is the number nets of screen, the materials can pass through the size of vibrating screen, it can be defined how many mesh the product is, such as 200mesh,that is the materials can pass the 1 inch * 1 inch including 200 mesh screen. By analogy, larger mesh, smaller materials, smaller mesh, larger materials."+" "-"before mesh says whether the materials can pass the mesh of screen."-" says the materials can pass the size of screen, that is the particle size smaller than the screen size; While "+"says the materials can not pass the size of screen, that is  the particle size larger than the screen size. For example, the particles - 100 mesh ~ + 200 mesh, that says these particles can pass the 100 mesh of screen, but can not pass the 200 mesh of screen. When at the leakage of this particles, it should be put the large mesh (200mesh) under the small mesh(100mesh),the materials in the large mesh screen is the purpose of 100 to 200 - particles.

Micron, we usually refers to the particle size of the powders (maximum length of particles).Such as:Special aluminum hydroxid H - WF – 100.Its particles is 100 microns, about 148 mesh, special aluminum hydroxide H - WF – 15,its particles is 15 microns, about 988 mesh.

The specific conversion table between mesh and μm

Mesh    μm     mesh      μm
2          8000      100        150
3          6700      115        125
4          4750      120        120
5          4000      125        115

According to the fineness, industrial grinder mill can be divided:

①     Coarse grinding:the fineness of raw materials are in the range of 40-1500mm.The fineness of products is 5-50mm.

②     Medium grinding:the fineness of raw materials are in the range of 10-100mm,the fineness of products is 5-10mm.

③     Fine grinding:the fineness of raw materials are in the range of 5-10mm,the fineness of products is below 100μｍ.

④     Superfine grinding: the fineness of raw materials are in the range of 0.5-5mm, the fineness of products is below 10-25μｍ.

The fineness of products:

12500mesh===1μｍ

Shanghai Jianye Company is a professional manufacturer of grinder mill. The grinder mill is applied to Barite, Marble, Granite, Limestone and other such as a certain hardness of ore.

According to the finished product size, it can choose a suitable grinder mill.

There is a very big relations between industrial grinder mill's finished product size and selection. According to the hardness of raw materials, the stuff size, the finished product size and output, Shanghai Jianye Company can design the pulverizing technologyfor free, and train the technicians at the scene of grinder mill.
