Mills usually operate in the range 65 - 82% of critical but values as high as 90% are sometimes used. A crucial parameter that defines the performance of a mill is the energy consumption. The power supplied to the mill is used primarily to lift the load (medium and charge). Additional power is required to keep the mill rotating. 8.1.3 Power drawn by ball, semi-autogenous and autogenous mills
