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

19-10-2017· There is a mathematical solution to this problem – the Bond formula. It uses to help determine the grinding media optimal size must be loaded into the ball mill for proper operation ensure. The calculation formula is below: B – the grinding balls diameter, mm; A – the correction factor (for grinding balls A = 20,17; for cilpence A = 18,15);
