How many kinds of grinding mills for stone superfine powder pulverizing?

Introduction
1) Product: superfine stone powder(calcite carbonate powder, chalk powder, limestone powder, dolomite powder, kaolin powder, bentonite powder , talc powder, mica powder, magnesite powder, pyrophyllite powder, ceyssatite powder, barite powder, gypsum powder, alunite powder, granite powder, fluorite powder, phosphate rock powder, kalium ore powder , float stone powder)
2) Finished fineness: 50meshes~3000meshes
3) Capacity: 0.5t/h~20t/h
Grinding mills details
a) HGM series grinding mills:
1. The grinding mills of HGM is high efficient (twice as much as jet mill, mixing grinder and ball mill)
2. The spare parts of grinding mills can serve much longer time (2-3 times longer than that of impact mill or turbo mill.
3. High safety and reliability of the ultrafine mill (no rolling bearings and screws in the grinding cavity, so no problems caused by the wear of bearings or screws)
4. The HGM Grinding mills are characterized by high fineness (final size: 325-3000 mesh, D97<5 micron)
5. Environment-friendly
b) YGMs series grinding mills:
CLIRIK YGMs series grinding mills are suitable for processing various non-flammable and non-explosive mineral materials with Moh’s hardness less than 9.3 and humidity less than 6%, it is widely used in the fields of metallurgy, construction, chemical industry, mining, highway construction etc,. The granularity of the finished powder size can be adjusted between 50 and 325 mesh (315-45 micron). Examples of processing materials include quartz, feldspar, barite, calcite carbonate, limestone, talc, ceramic, iron ore, carborundum, bauxite, rock phosphate, coal and other materials, total about 400 kinds of materials.
