As mentioned earlier, pebble mills are widely used in the north american taconite iron ore operations. since the weight of pebbles per unit volume is 3555 of that of steel balls, and as the power input is directly proportional to the volume weight of the grinding medium, the power input and capacity of pebble mills are correspondingly lower.
The number of impacts in primary ball mills are far more frequent but have less magnitude than those experienced in sag mills. the increased frequency is due to the increase in charge volume 35 40 versus 5 10, higher mill speeds, and the larger number of balls per unit charge weight.
