Description: This air swept coal mill is specially used to dry and grind coal. And it is mainly consist of feeding device, main bearing, rotary part, transmission device, high voltage starting device, and lubrication system. Featuring rational structure and high grinding efficiency, this air swept coal mill is an ideal choice for coal pulverization.
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.
Parameter
- Running available, continuously working and high capacity.
- Less drive part, and low maintenance cost.
This mill was designed based on open circuit system, and it was advanced compare with traditional ball mill. And the production capacity has been improved a lot. It can produce cement with more fineness, high blaine, it is a advance grinding equipment for high standard cement.
