Coal gangue is the process of coal mining and coal washing discharge of solid waste, is a kind of associated with coal in the process of coal than a low carbon content, coal rock hard dark gray. Including the waste rock, mining process in the process of drivage extraction from the roof, floor and interlayer singled out in the process of waste rock and coal washing washing waste rock.
Coal micronizer mill profile:
Coal micronizer mill is mainly suitable for middle and low hardness, non flammable and explosive of mohs hardness level 6 or less brittle material of ultrafine powder processing, such as calcite, chalk, limestone, dolomite, carbon black, kaolin, talc, mica, bentonite, magnesite, illite and pyrophyllite, vermiculite, sepiolite, attapulgite, rectorite, diatomite, barite, gypsum, alum stone, graphite, fluorite, phosphate rock, potassium ore, more than 100 kinds of materials, such as pumice powder product granularity between 325-3000 mesh adjusted, production could reach 0.7 7.5 tons per hour.
Mill gangue, coal gangue powder processing equipment performance characteristics:
1, efficient, low consumption. In the finished materials, power, under the condition of same fineness, 40% higher than that of the jet mill and mixing mill production.
2, long service life. Under the condition of the same material and finished product fineness, impact crusher and turbine crusher wear parts service life is long, generally can reach more than 1 year.
3, grinding chamber without rolling bearing and screw. Bearing and seal and will not destroy machine screw loose, etc.; Product fineness can reach d97 5 microns or less at a time.
