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 ...
Energy Use in Comminution. Grinding activities in general (including coarse, intermediate, and fine grinding) account for 0.5 pct of U.S. primary energy use, 3.8 pct of total U.S. electricity consumption, and 40 pct of total U.S. mining industry energy use. Large energy saving opportunities have been identified in grinding in particular.
