An air swept ball mill also called air swept coal mill is a type of coal mill commonly used in industrial grinding systems for pulverizing coal and other materials. This mill uses the flow of air to carry the pulverized coal upward from the grinding zone to the classifier.
The continual use of air-swept ball mills in preference to grate discharge mills in coal power stations is largely due to the ease of transportation of pulverised coal particles out of the mill coupled with the benefit of pre-classification. The fine coal particles are elutriated from the mill by the air flow to the classifier.
