This grinding mii is a equipment which produces thin powder and super thin powder. It is applicable to non-flammable and non-explosive materials with hardness less than 6, such as calcite, chalk, limestone, dolomite, kaolin, bentonite, talcum, talc, magnesite, illite, pyrophyllite, vermiculite, sepiolite, attapulgite, rectorite, diatomite, barite, gypsum, alum earth, graphite, fluorite, variscite, potash ore, floatstone.

The rotating turbine in the collector makes the coarse particles fall back for regrinding. The fine particles will come into the cyclone collector with the airflow and discharged by the discharging valve on the bottom of the collector. They are the final products. The airflow with little dust will be discharged through blower and muffler after being purified by the cyclone collector.
