Ball Charge and Grinding Efficiency - Grinding ...
The volume of grinding media in a mill is directly related to grinding efficiency. The higher the volume of grinding media the more effective the grind. Balls must be added to maintain the media load and mill power draw. The power draw increases as balls are added and decreases as media wears down: add balls.

Ball mill - Wikipedia
Key properties of grinding media are size density hardness and composition. Size: The smaller the media particles the smaller the particle size of the final product. The grinding media particles should be substantially larger than the largest pieces of material to be ground. Density: The media should be denser than the material being ground.
