A typical circuit, as shown in Figure 2, can consist of either an Autogenous (AG), SemiAutogenous (SAG) combined with a ball mill. In an AG mill no grinding media is added, while in SAG mills the charge is supplemented with steel balls. As more steel balls are added the transition from a SAG to a ball mill occurs.

Bond work index: Wj= kWhlshort ton From Eq. (6), the specific grinding energy is: W = kWhlshort ton or W = kWhlt For throughput 400 tIh production, the total required ballmill power is: kWhlt x 400 tIh = 34092 kW. If six (6) ballmills are used, the power drawn from each mill is: (34092/6) = 5682 kW.

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 3045%). Pulp (crushed ore and water) fills another 15% of the drum's volume so that the total volume of the drum is 50% charged.
