CHAENG Coal Mill is also called the air swept coal mill. It is used for grinding and drying the coal with all kinds of hardness. Application :Power plants, cement plants, lime plants and other coal grinding enterprises Capacity :12-38 t/h Motor Power :280-1250 kW Fineness :80 μmR 3% The coal mill can be divided into low speed coal mill, medium speed coal mill and high speed coal mill. These three kinds of coal mills have their own good points, customers can choose each one suitable for production according to the actual demands. The energy saving ball mill is a horizontal cylindrical rotating device, which has two cabins. Coal mill is energy saving grate ball mill and the outside runs along the gear. The materials enter the first cabin of the mill spirally and evenly through the feeding apparatus and hollow shaft. In the first cabin, there is stepped liner or corrugated liner, and steel balls with different specifications. The centrifugal force generating from the rotation of the cylinder brings steel balls to a certain height, and then the balls fall, thumping and grinding the materials. After coarse grinding in the first cabin, the materials enter the second cabin by single-wall partition. There is flat liner and steel balls in the second cabin, where the materials are grinded further. Finally, the powder is discharged through discharge grate and the grinding operation is finished.
