The mill charge volume has a great impact on grinding efficiency. For efficient grinding autogenous (AG) and semi-autogenous (SAG) mills need to be operated with the correct charge in order to maximize their throughput while avoiding overloading. The Outotec MillSense sensor system gives a precise indication of the mill charge volume.

Estimates the charge volume of a grinding mill based on the number of exposed lifters. By counting the number of lifters showing (during a mill shutdown) and comparing to the total number of lifters (including those buried in the charge) the fraction of the mill under the charge is determined.
