Ball Charge and Grinding Efficiency - Grinding ...

In ball mills all the media is balls with a high SG so the impact of pooling is not as large. Additionally, in ball mills grinding is primarily through cascading not cataracting (compared to an AG.SAG) so the slurry pool is not a factor unless density is high, which leads to viscosity issues.

Mill (grinding) - The Full Wiki

The SAG mills use a minimal ball charge of 6 to 15%. A rotating drum throws large rocks and steel balls in a cataracting motion which causes impact breakage of larger rocks and compressive grinding of finer particles. Attrition in the charge causes grinding of finer particles. SAG mills are characterized by their large diameter and short length.
