Abstract For dry ball mill grinding operation, the effect of ball and mill diameters on grinding rate parameters of the size-discretized population balance model has been investigated for quartz, limestone, a soft cement clinker and a hard cement clinker. Experiments were performed in three mills of 29.2, 40.6 and 61.0 cm diameter. The diameter of the balls used ranged from 1.27 to 3.81 cm.
Grinding experiments were performed in a laboratory sized ball mill. The parameters and operating conditions used are listed in Table 2.For each test, a charge of 460 g of one of the six size fractions of clinker was fed into the mill, and the sample was ground for various periods of time: 0.5, 1, 2, 4, 6, 8, 10, 20 and 30 min (a different 460 g sample was used for each time period).

The effects of percent solids, mill loading, and grinding time on product size distribution and ball wear were studied in a laboratory ball mill for a taconite ore. Mild steel balls and HCLA steel balls were used to examine the role that ball hardness play in grinding. Net production of −44-µm (−325-mesh) material reached maximum at 70% solids, whereas the ball wear decreased as pulp ...
