An overfilling indicator for wet overflow ball mills ...

The increased mill charge load will lead to an increase in mill power draw. The onset point of overfilling an AG/SAG mill can be indicated when the mill power draw exceeds the safe operation power threshold. In a ball mill, however, the mill power draw is dominated by ball media charge volume for a given mill rotational speed.
