Another key factor is ball mills charging that can set plants back if done mistakenly. To our experience, several mineral processing plants today suffer from malpractices in grinding balls and liner selection. This has brought about several, perhaps invisible, costs to the mining industry. Bad choice of grinding media and liners will sace ...

SAG mill base power was estimated from pilot plant data at kWh/t, the basis was a SABC circuit of 8% ball charge. Maximum SAG mill power was determined by deducting the installed ball mill pinion power of kWh/t from the maximum overall circuit power of kWh/t to give kWh/t. Overall power for the comminution circuit (SAG plus ...

general, the bigger the mill diameter, the lower are the mill operating and critical speeds. Thus, for larger mills the number of poles will increase. As a result, the number of poles can vary from 48 to 72 poles (Fig. 3.) with typical mill speed requirements of about 10 rpm for larger SAG mills and about 15 rpm for smaller ball mills. Figure 3.
