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 A simplified picture of the mill load is shown in Figure

study of the effect of the various parameters on the performance of a ball mill. The parameters studied in this work are particle size, number of balls, time of grinding, particle density, and speed of the ball mill (rpm). An attempt has been made to develop correlation for the performance of the ball mill by correlating these variables with the grindability on the

In the wet grinding process of a stirred media mill the bead size, the specific weight of the grinding media, and the mill speed influence the milling efficiency. When using grinding media with a higher specific weight, it is possible to reduce the bead size without losing milling energy by equal bead filling volume.
