increased "ball-charge participation." Over throwing should be avoided, especially high-energy ball-on-shell impacts just above the charge toe, owing to the risk of ball-on-liner damage and excessive metal flow. In fixed-speed mills, this may be achieved by increasing charge volume; in variable speed mills, this may be achieved by reducing mill

Wills' Mineral Processing Technology - ScienceDirect

Media ball sizes, for example, range from about 20 mm for fine grinding to 150 mm for coarse grinding. Tumbling mills are typically employed in the mineral industry for primary grinding (i.e., stage immediately after crushing), in which particles between 5 and 250 mm are reduced in size to between 25 and 300 µm.
