Air Swept Coal Mill Diagram. Air Swept Coal Mill Working Principle. First, the raw coal is fed into the feed chute by the feeding device. Then, the hot air with a temperature of about 300 ℃ enters through the air intake pipe and begins to dry the raw coal while they are falling. After that, the raw coal will be sent into the mill chamber.
