Ball Mill - an overview | ScienceDirect Topics

Since the weight of pebbles per unit volume is 35–55% 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 Thus, in a given grinding circuit, for a certain feed rate, a pebble mill would be much larger than a ball mill, with correspondingly a higher capital

Rod mills, how they function - mine-engineer

Rod mills normally carry 35 to 65% rod charge by volume The limits on charge level are (1) keeping the feed end trunnion open so that feed will get into the mill, and (2) keeping the rod charge low so rods will not work their way into discharge openings where they can cause rod tangling The Critical Speed is used for the determination of ball mill ideal operating speed But for comparison
