Coal mill is the equipment used for grinding and drying coal with different hardness and it is mainly composed of feeding device, principal axis, rotating part, transmission part, discharging part, high-pressure starting device and lubrication system.
Coal mill is widely used cement, building material, thermal power generation, metallurgy and chemical industry and it has the reasonable structure and high powder grinding efficiency, so that it is the ideal equipment for making coal powders.
This grinding mill adopts edge driving and the electro-motor rives the grinding mill through the reducer and rack wheel and pinion. The grinding mill adopts air-swept structure with a drying bin, so that it had strong adaptability to the water containing in the raw coal.
Inside the powder grinding cabin, the ladder lining board, double-ladder lining board and ripple lining board are arranged in a combined type, thus improving the powder grinding ability of the grinding mill. The feeding device adopts window-shade structure that the air can obliquely go in, thus enhancing the heat exchange ability of the grinding mill and effectively avoiding the material blockage of the feeding mouth of the coal mill.
