Therefore the plant took the sound reading as an indicator of changes in SAG load for milling circuit control. Other systems adjust mill speed in response to acoustic information to control the mill load and ensure maximum grinding efficiency by moving the point of impact to the toe of the charge (Pax et al., 2014).
