CHARGING GRINDING MEDIA Grinding & Classification
2022-7-27 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.

Ball Mill an overview ScienceDirect Topics
Modern ball mills consist of two chambers separated by a diaphragm. In the first chamber the steel-alloy balls (also described as charge balls or media) are about 90 mm diameter. The mill liners are designed to lift the media as the mill rotates, so the comminution process in the first chamber is dominated by crushing.
