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 ... While the media charge should always be 50, material charge will vary from 25 to 40 or more in some cases such as when
Numerous torque mill tests, in addition to the growing plant data base compiled to date, show that media charging near the size that provides highest ball mill grinding efficiency provides a degree of robustness with changing ore grindability. It is rare that the media is incapable of breaking the largest particles as they become tougher.
