Feed size：＜25mm
Motor Power：95-1250KW
The raw coal enters the feeding device of the air-swept coal mill from the feeding equipment, and the hot air with a temperature of about 300°C also enters the feeding device through the air inlet pipe. The drying bin is equipped with a special lifting plate to raise the raw coal. The raw coal is dried here through intense heat exchange, and the dried coal enters the grinding bin through the double-layer partition board equipped with lifting plates. Grinding body (steel ball) is installed in the grinding chamber, and the coal block is crushed and ground into coal powder in this chamber. While the coal is crushed, the pulverized coal powder and gas will be taken out of the mill through the discharge device of the air-swept coal mill by a special induced draft fan, and the coarser particles will be returned through the return screw of the discharge device. Go to the grinding chamber for re-grinding.
100% product on-site real shooting, so you can rest assured of your choice!
Capable of continuous production, large production capacity, high grinding efficiency, easy adjustment of fineness, and low energy loss.
It has strong adaptability to materials, and can grind and dry coal with various hardness.
The feeding device of this mill adopts a louver-type structure with oblique wind and oblique feeding, which enhances the heat exchange capacity of the coal mill and makes the feeding more smooth, so as to effectively prevent the material blocking phenomenon at the entrance of the coal mill.
The equipment has compact structure, less transmission parts, low maintenance cost, stable operation and convenient installation.
