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
