Powell, Yahyaei, Mainza, Tavares. Presented at the AusIMM Mill Operators Conference Brisbane, Australia 23 - 25 June 2021. ABSTRACT. Maintaining the work balance between the primary SAG mill and secondary ball mill(s) is an overlooked bottleneck, and thus opportunity, in an increasing number of circuits worldwide.

Material transport problems in ABC/SABC circuits with pebble crusher In ABC/SABC circuits, the AG or SAG mills are in closed circuit with screens and pebble crushers. The mill discharge from these mills consists of slurry, which goes to ball mills for further grinding, and coarse pebbles/rocks, which are crushed and sent back to the mill.

Cerro Verde reports lower energy consumption when compared to SABC circuits. Cerro Verde actual data shows that the HPGR circuit energy consumption was 3 kWh/t less than the SAG/Ball mill circuit that was considered in the trade off studies. The initial trade off studies were expecting to have 4.2 kWH/t of less energy consumption.

The results showed that the HPGR - ball mill circuit achieved a 21% reduction in energy consumption over the existing SAG - ball mill circuit at the same P80 grind size of 160 μm. At a grind of 80% passing 75 μm, the HPGR - stirred mill circuit showed a 34% reduction in energy compared to the base case.
