Charging a Dry Mill The general operation of a grinding mill is to have the product impacted between the balls as they tumble. If there are insufficient solids in the mill then the media will strike itself and generate excessive media wear. If too much product then the solid may buffer the impact too much.
Grinding media management in ball mills. Grinding ball additions. Grinding balls should be added each shift. Mill performance is negatively impacted when the mill is not drawing power at targeted level. This results in coarser grind size or loss in throughput. The grinding balls can be added onto the mill feed conveyor when the mill is running.
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.

We can calculate the steel charge volume of a ball or rod mill and express it as the % of the volume within the liners that is filled with grinding media. While the mill is stopped, the charge volume can be gotten by measuring the diameter inside the liners and the distance from the top of the charge to the top of the mill.
