Coal Miller

Application and Usage Range:

Coal Miller is major equipment of cement plant and used for drying and grinding coal. The equipment mainly consists of feed device, main bearings, rotating parts, drive device, selling device, high-voltage start-up device and lubrication system.

The raw material is fed into mill by feeding equipment. The hot wind enters into the mill by inlet end. As the mill cylinder rotates, the coal and hot air exchange heat in the mill. The coal is crushed and ground in the mill. When the coal is ground, the powder is brought out of the mill by the hot air going through the mill. Compared with rock grinder, the coal mill we make is with reasonable structure, high grinding efficiency and is the ideal equipment for coal processing.

Make the safe operation of Coal Miller

1. change the piling method of the coal to make the coal accumulate little amount, thus avoiding the spontaneous combustion of the coal.

2. change the gap of the great bar from 25mm to 22mm; thus decrease the wind speed and increase the drying speed.

3. add a settling chamber between the coal mill and the pipe; thus prevent the hot coal powder enter the coal grinding mill.

4. add a explosion-proof valve at the opening.

5. increase the fineness of the coal from 10% to 15%.

6. make up strict safety rules.
