Air swept ball mill - ALLIS CHALMERS MFG CO
Air swept ball mills for grinding dry materials are well known in the art. It is also well known to provide a discharging chamber in such mills distinct from the grinding space proper. An object of this invention is to provide a simple, improved discharge and classifying chamber for air swept ball mills, having a diaphragm and frusto-conical screen for separating and discharging fine and coarse materials.

Control of the mill charge behavior in dry tumbling
1999-1-1 The discharge rate of the swept material from the mill is dependent on the air flow rate, mill rotational speed, ball filling and fineness of the mill content. High air flow rate, and high mill speed, can provide higher circulating loads in the circuit, as more material is discharged from the mill, providing shorter retention time and consequently higher circuit capacity.
