    Raw materials enter into the mill by the feeding device, and the hot air gets into the mill through the air tube. When the mill cylinder begins to rotate, coal and hot air can exchange heat with each other. Meanwhile, the coal will be crushed and grinded in the air swept coal mill. While the coal is grinded, fine powder will be taken by the hot air out of the mill through the discharging device.
