WEBMay 8, 2017 · Thus the power to drive the whole mill. = + = = 86 kW. From the published data, the measured power to the motor terminals is 103 kW, and so the power demand of 86 kW by the mill leads to a combined efficiency of motor and transmission of 83%, which is reasonable.
WEBBoth mills differ in terms of the efficiency of grinding. Ball Mills have a higher degree of efficiency than SAG Mills due to their smaller size and have more area for grinding particles, leading to faster grinding. On the other hand, SAG Mills have a larger and deeper drum that provides larger lifting force which increases grinding efficiency.
WEBNo, it is not normal to operate above 40 to 45% charge level.
