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.

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.

Calculating Power Draw when sizing Ball Mills. Im interested to know when sizing a new ball mill, as to why recirculating load has no effect on the power calculation, although it will have effect on volumetric capacity naturally. For instance a mill of 300tph with a 300% recirculating load would have 1200tph going through effectively, but if we reduce the recirculating load to 200% at 900tph ...
