Coal gangue is a kind of solid waste discharged in the process of tunneling, mining and coal washing. It is a kind of black gray rock with low carbon content and harder than coal, which is associated with coal seam in the process of coal formation. The
Coal gangue is a kind of solid waste discharged in the process of tunneling, mining and coal washing. It is a kind of black gray rock with low carbon content and harder than coal, which is associated with coal seam in the process of coal formation. The carbon content is 20 % ~ 30 %. Coal gangue is mainly used to produce gangue cement, concrete lightweight aggregate, refractory bricks and other building materials, can also be used to recover coal, coal and gangue mixed burning power generation, preparation of crystalline aluminum chloride, water glass and other chemical products and extraction of precious rare metals, also can be used as fertilizer
Coal gangue milling is generally divided into coarse powder processing ( 0-3mm ), fine powder processing ( 20 mesh-400 mesh ), ultra-fine powder processing ( 400 mesh-1250 mesh ) and micro powder processing ( 1250 mesh-3250 mesh ) four types.
Large coal gangue crushed by crusher into the mill feeding fineness ( 15mm-50mm ). The crushed small coal gangue is sent to the hopper by the hoist, and then sent to the grinding chamber of the mill uniformly and quantitatively by the vibrating feeder for grinding.
LM vertical mill, MTW European version mill and 5X European version intelligent mill can be selected for fine powder processing. Ultra-fine powder processing is generally selected LUM ultrafine vertical mill, MW ring roller mill, coarse powder processing CM European coarse grinding, straight-through centrifugal mill.
The coal gangue powder after grinding is classified by the powder selecting machine, and the unqualified powder is classified by the powder selecting machine and returned to the host machine for regrinding.
The powder that meets the fineness enters the dust collector through the pipeline for separation and collection. The collected finished powder is sent to the finished silo by the conveying device through the discharge port, and then uniformly packaged with a powder tanker or an automatic baler.
