Energy and Cost Comparisons of HPGR-based Circuits | E & MJ

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 HPGR-stirred mill circuit showed a 34% reduction in energy compared to the base case.

HPGR High Pressure Grinding Rolls - Mineral Processing & Metallurgy

When is HPGR better than Ball Mill. HPGR is typically used in a third-stage or fourth-stage crushing application ahead of grinding. You could always try to build a circuit doing 45 µm classification, but I suspect your circulating load would be overwhelming. Most HPGR applications in hard rock mining achieve 3000 µm to 7000 µm product
