Ore is processed in a single grinding line consisting of a 7,000 kW single pinion SAG mill (8m x 8m) with pebble recycle and a 14,000 kW dual pinion ball mill (8m x 13m) operated in closed circuit with a 24 cyclone cluster to achieve a primary grind with a P80 of 90 microns.
The number of SAG mill revolutions required to grind the material to a P 80 of mm is used to predict AG/SAG specific energy using quation 4. Correction E factors for feed size and pebble ing are applied to the AG/SAG specific energy, as well as specific crush energy adjustment from mm to the mill transfer size T 80 using Bond's Law (Starkey Larbi, 2012). The Bond equation is used ...
