More2018-12-4 The test mill (Fig. 2) is 0.6 m (2 ft) inside diameter by 0.2 m (0.67 ft) inside length. It is operated at 65 percent of critical speed. Each ball charge is close to 95 kg (209 lb), occupying 34 percent of the mill volume. Balls are used that represent a fully graded charge based on constant wear rate in a continuously operating mill. Slurry volume occupies the 40 percent voids volume in the 34 percent ball charge. The drive shaft is torque-metered and records once per second. Drive losses (a roller bearing between the mill and the torque meter) have been measured to be negligible. Media charges were prepared by weighing and counting out the number of balls needed in each size class, determined by their individual weights and the specific gravity of steel. Twenty-seven equilibrium media charges are currently available for testing. Examples are given in Table 1.The test mill
