Ultrafine grinder mill is a new kind of machine for producing fineness and ultra-powder. It is mainly used for grinding the materials, whose hardness is middle and low, moisture below 6%, and Ultrafine mill Moths hardness should be blow 9 grade and non-explosion and non-flammability, such as: Calcite, chalk, limestone, dolomite, kaolin, bentonite, steatite, mica, magnetite, iolite, pyrophillite, vermiculite, meerschaum, attapulgite, diatomite, barite, gypsum, alunite, graphite, fluorite, phosphate ore, potassium ore pumice, etc.
Ultrafine grinder mill structure and features:
Ultra fine mill is mainly composed of a host, analyzer, blower, finished powder cyclone, cyclone separator and duct, wherein, the host is composed of a machine frame, air inlet volute, blade, grinding roller, grinding ring, a cover casing. Ultra fine grinding machine can replace the Raymond mill, smoothly produce ultrafine powders, fineness of which can be adjusted freely between 325-2500 mesh.
