### 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. Equation 1 is multiplied by the factor of 1.08. A multi-compartment ball mill consists of two or more grate discharge ball mills in series. The same equation is used to calculate the power that each ball mill compartment should draw.
