One obvious reason is that impact energies in laboratory mills are negligible compared to those in industrial mills. For example, Dodd et al. (1985) have estimated that an increase in ball kinetic energy from 1.4 J for a 0.025 m ball in a 0.20 m ball mill to 350 J for a 0.127 m ball in an 8.5 m ball mill.

Analysis of Variant Ball Mill Drive Systems. The basic element of a ball mill is the drum, in which the milling process takes place (Figure 1). The length of the drum in the analyzed mill (without the lining) is 3.6 m, and the internal diameter is 3.4 m. The mass of the drum without the grinding media is 84 Mg.

Crushed ore is fed to the ball mill through the inlet; a scoop (small screw conveyor) ensures the feed is constant. For both wet and dry ball mills, the ball mill is charged to approximately 33% with balls (range 30-45%). Pulp (crushed ore and water) fills another 15% of the drum's volume so that the total volume of the drum is 50% charged.

For modern large gold plants, the most typical flowsheets are crushing circuits (for heap leaching), autogenous/semiautogenous (AG/SAG) ball-mill circuits, or HPGR-ball-mill circuits. Such flowsheets dominate the 20 largest gold producers in Table 17.1. Examination of the flowsheets within each category, though, also demonstrates that …
