The mill uses airflow to convey feed material to the mill's grinding chamber, classifies the ma-terial into fine and coarse fractions, recirculates the coarse fraction for further grinding, and conveys fine particles out of the mill, all in one continuous operation. Another benefit of the air classifier mill is its versatility.
