The grinding chamber is equipped with the grinding body (steel balls), coal in this chamber will be crushed and ground into pulverized coal. When the coal is crushed, the induced draft fan dedicated through feeding device will move pulverized coal and gas out of the mill, the coarse particles will return to the grinding chamber through the spiral feeding device for the re grinding.

The particles do not grind as easily as coal, especially when mixed with coal. The particles will eventually build an inventory in the mill and can overload the grinding table. You will probably notice an increase in mill power and some vibration, which can be severe. The mill throughput will be reduced due to the power increase, vibration, and differential pressure caused by the excessive
