Application: air swept coal mills are the main equipment of cement plants for drying and grinding coal powder. The equipment is mainly composed of a feeding device, a main bearing, a slewing part, a transmission device, a high-voltage starting device and a lubrication system. The raw materials are loaded into the mill by the feed through the feeding equipment, and the hot air enters the mill through the air inlet pipe. With the rotation of the mill barrel, the coal and hot air exchange heat in the mill, and the coal is crushed and ground in the mill. when the coal is being ground, the fine powder passes through the hot air in the mill and is taken out of the mill through the discharge device.

Characteristics: The air swept coal mill is driven by the edge. The electric motor drives the mill through the reducer and the gears. The air swept coal mill adopts an air swept structure with a drying chamber, which makes the coal mill have a large adaptability to the moisture of the raw coal. The grinding chamber uses a stepped liner, a double stepped liner, and a corrugated liner in order. The combination arrangement and other arrangements improve the grinding ability of the coal mill. The feeding device adopts a louver structure with oblique air inlet, which enhances the heat exchange capacity of the coal mill and can effectively prevent the blockage of the coal mill inlet.

Working principle: Raw coal enters the feeding device of air swept coal mill from the feeding equipment, and hot air at about 300 ° C also enters the feeding device through the air inlet pipe. and the special lifting material in the drying warehouse lifts the raw coal, so that the raw coal undergoes strong heat exchange here to be dried, and the dried coal block enters the grinding bin through the double-layer partition board. A grinding body (steel ball) is installed in the grinding chamber, and the coal block is pulverized and ground into coal powder in the chamber. At the same time as the coal block is crushed, the special induced draft fan passes through the discharge device of the air swept coal mill to bring the pulverized coal powder and gas out of the mill together. The coarser particles will return through the return screw of the discharge device and is ground again in the grinding chamber.
