Mill Charge - an overview ScienceDirect Topics

8.3.1 Rod Mill Charge. Rod mill charges usually occupy about 45% of the internal volume of the mill. A closely packed charge of single sized rods will have a porosity of 9.3%. With a mixed charge of small and large diameter rods, the porosity of a static load could be reduced even further.

PERI™ AutoCharge Mill Grinding Ball Charging System

When charging a grinding mill, the standard practice is to dump tons of balls into the mill at once and replace them somewhere between once a shift and once a week. It’s an inefficient practice that wastes energy, impacts product particle size distribution and risks breakage of mill linings and grinding media.
