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 ...

of the Bond ball mill grindability test. For all model based methods, a reliable method to calculate mill power draw for a given mill is required for the calculation of power draw. Morrell (1996) proposed a mathematical model for autogenous, semi-autogenous and ball mills which is based on the motion of grinding charge inside the mill.

the mill power and the efﬁciency of the mill operation (Van Nierop and Moys, 2001). If a SAG mill has been designed with a conventional power or speciﬁc energy model which do not con-sider the projected feed size distribution it is likely that this mill will reach the expected power consumption but will not satisfy
