Further tests were done, using samples from a platinum mine, namely the feed to a secondary mill (ball-mill) and rounded pebbles from a primary AG mill. Grinding capacity was maintained over the range 0–30% pebbles, by volume, with savings in energy and ball consumption increasing progressively. At 25% pebbles, the saving in energy was 18% and the pebble consumption was about 7% of total

Table 3 is a summary of the preliminary tests (in duplicate) using various proportions of balls and pebbles. The on-line torque measurement was used for early measurement of the power drawn by the mill, so that the grinding time could be calculated, to maintain the same amount of energy for all tests (i.e. assuming a constant grinding efficiency).

An increase in the mill speed will give a directly proportional increase in mill power but there seems to be a square proportional increase in the wear. Rod mills generally operate within the range of 60—75 % of critical speed in order to avoid excessive wear and tangled rods. Ball and pebble mills are usually operated at 70—85 % of critical speed. For dry grinding the speed is usually
