An overfilling indior for wet overflow ball mills
The lack of constraints in ball mill capacity in the published ball mill models may result in unrealistic predictions of mill throughput. This paper presents an overfilling indior for wet overflow discharge ball mills. The overfilling indior is based on the slurry residence time in a given mill

Calculating Power Draw when sizing Ball Mills Grinding
2019731&ensp·&enspThis means the residence time goes down but the power doesn't really change that much. On the other hand, for SAG mills with grate discharge, the charge level is a bit more variable, so you do sometimes see higher SAG mill power or mill load levels at higher circulating loads.
