    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 A simplified picture of the mill load is shown in Figure 8.3 Ad this can be used to establish the essential.Usually, tumbling mills power equations have been derivate from mechanics as the product of torque and rotational speed. Models for the prediction of the power drawn by ball, semi autog enous and fully autogenous mills have been developed and cited in the technical literature (Turner, 1982 Austin, 1990 Moys, 1993 Morrell, 1996).
