Grinding plant (also known as calcite micro-grinding, limestone micro-grinding mill, calcium carbonate micro-powder mill, talc micro-powder mill, barite micro-powder mill, gypsum micro-powder mill, marble micro-powder mill, feldspar micro-powder mill, fluorite micro-powder mill is mainly suitable for ultra-fine powder processing of non-inflammable and explosive brittle materials with medium and low hardness and Mohs hardness ≤6, over 200 kinds of raw materials can be grinded: it can also be used for pulverizing materials with hardness less than 6 in Moh’s scale and humidity less than 6 percent such as kaolin, limestone, basalt, calcite, marble, talcum, barite, gypsum, dolomite, bentonite mud, mica, pyrophyllite, sepiolite, carbon black, dolomite, graphite, alunite, fluorite, potassium feldspar, phosphorite, pigment, up to 200 kinds.The fine powder finished product can be adjusted arbitrarily between 325-3000 mesh, and the output can reach 0.4-4.5 tons per hour.

The whole set of grinding mill production line consists of Jaw crusher(for big ores stone), hammer crusher, bucket elevator, storage hopper, vibrating feeder, main unit, inverter classifier, cyclone collector, pulse deduster system, high pressure positive blower, air compressors and electrical control systems.
