Thus, in a given grinding circuit, for a certain feed rate, a pebble mill would be much larger than a ball mill, withcorrespondingly a higher capital cost. However, theincrease in capital cost is justified economically by a reduction in operating cost attributed to the elimination of steel grinding media.
