High-pressure grinding rolls (HPGRs) have struggled for acceptance into the hard-rock mining sector. CRITICAL HPGR PARAMETERS HPGR roll diameters typically range from 0.5 m to 2.8 m, depending on the supplies, and roll widths vary from 0.2 m to 1.8 m. The aspect ratio of the rolls also varies as a function of manufacturer. Typical HPGR throughput rates range from 20 to 3,000 tph, withA Pilot-Scale Examination of a High Pressure Grinding Roll,For HPGR pilot-scale evaluation, tests were carried out to assess the influence of different processparameters on comminution performance. These tests included the variation of specific pressing force, aswell as closed-circuit testing with a 4 mm screen.
