Air Swept Coal Mill

Air swept coal mill is used for drying and grinding pulverized coal. It mainly consists of feeding device, main bearing, rotary part, transmission device, ballast device, high-pressure starting device and lubrication system. Raw materials are loaded into the mill by feeding equipment, hot air enters the mill through the air inlet tube. With the rotation of the mill barrel, coal and hot air exchange heat in the mill. Coal is crushed and ground in the mill. While coal is grinded, fine powder is taken out of the mill through the hot air in the mill and through the discharging device. The air sweeping coal mill has reasonable structure and high grinding efficiency. It is an ideal equipment for the preparation of pulverized coal.
