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.
