What is the particle size of the minimum finished product of roller mill?

Due to the development of the grinding industry, roller mill is the leading grinding equipment in the industry. More and more industries require the processing of ultrafine powder, such as 400 mesh, 20 micron, etc. What is the particle size of the roller mill? Can it meet the requirement of superfine powder processing? Here's an analysis:

 

The roller mill is pided into many models according to the number of grinding rolls. According to the size of the material, it can be pided into: ordinary roller mill, high pressure roller mill, ultra-fine roller mill, micro-grinding mill, etc. The output particle size of ordinary roller mill is 0.247- 0.045mm, which is between 40 and 325 mesh. So the ordinary roller mill is not suitable for the grinding of superfine powder. The superfine roller mill is suitable for the production of ultra-fine powder, the highest material particle size can reach up to 1200 mesh, and the particle size of the micro-powder mill can be adjusted arbitrarily between 500 and 3500.

 

Calcium carbonate powder composite slurry with water, dry mill grinding calcium carbonate in the grinding water, after the completion of wet grinding calcium carbonate has joined in the grinding water, precipitation type calcium carbonate in the reaction with water, after the reaction concentration (dehydration), grinding both dry and wet way, its viscosity change situation is similar, can be 75-78% of mixture slurry concentrations
