Advantages

Air-swept coal mill is a kind of mechanical equipment that crushes and grinds coal briquette into pulverized coal, which is also important auxiliary equipment of pulverized coal furnace. When grinding coal in coal mill, it is mainly through crushing, shredding and pulverizing. Air-swept coal mill is main equipment of cement plant, which is mainly used for drying and grinding pulverized coal.

Coal Mill

Air-swept coal mill is mainly used to grind coal with all kinds of hardness, which is also suitable for ore grinding operation of cement, metallurgy, chemical industry and other industries.

Working process: raw materials are sent to grind mill through feeder and rotate with mill cylinder after the hot air entering the grinding mill, then coal and hot air carry out heat exchange. While the coal is crushed and ground, fine pulverized coal will be discharged from the discharge opening of mill driven by hot air.
