How to operate an air classifier mill to meet your fine

An air classifier mill applies impact grinding and air clas-sification in one step. 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.
