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 mircons (μm). At a grind of 80% passing 75 μm, the High pressure grinding rolls (HPGR) are used for particle reduction in mining operations and aggregates production. Known for energy efficient reduction, HPGRs are most often utilized when the processed material is hard rock.
