Grinding efficiency has been increased by the switch to an ANI 8.53-by-4.27-m semi-autogenous mill, the first of its kind in North America, installed in 1998. Savings accrue by virtue of the mill's size and design. It has the same throughput as two primary ball mills, and the SAG mill produces a finer grind than the ball mills.
The SAG mill feed conveyor discharges directly into the SAG mill feed hopper. The SAG mill discharge is screened via a 12 mm x 30 mm aperture trommel screen before gravitating to the mill discharge tank. Screen oversize is conveyed to a single pebble crusher, where it is crushed to below 12 mm prior to recycling back to mill feed conveyor.
circuits. As it turned out, designers are now adding secondary or pebble crushers to SAG circuits, on both greenfield and retrofit projects, to increase feed rate to the SAG mill. In other words, crushing plants, from primary to quaternary circuits, are here to stay.
