CRITICAL HPGR PARAMETERS. HPGR roll diameters typically range from m to m, depending on the supplies, and roll widths vary from m to 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, with installed motor power as high as 3,000 kW per roll.

Grinding of mineral mixtures in highpressure grinding rolls

Grinding of mineral mixtures in highpressure grinding rolls

First of all, a quick glance at these plots shows how much greater is the grindability of limestone as compared to quartz. In the case of feed, the grindability of limestone is t/kWh whereas that of quartz is t/kWh. The grindability of a mineral depends not only on its hardness, but also on its toughness.
