Figure 2 shows the active grinding area for an optimally charged ball mill. As the drum rotates, the media should ideally form a sloping pile that maintains a 45 degree angle so that there is a constant cascading of media at the surface. Because the media is falling the fastest and for the longest distance at the top of the pile, the majority
