HPGR High Pressure Grinding Rolls | Weir

What is HPGR? Used in mining applications for the last 30 years, high pressure grinding rolls (HPGR) reduce particles by compressing and crushing the feed between two counter rotating, parallel rollers with a small gap between them. This forces the rocks against each other and compresses the feed's density to 80% of its solid volume ...

HRC™e high pressure grinding rolls (HPGR) - Metso Outotec

Metso Outotec is the only OEM to successfully operate reliable flanges. The flange rolls eliminate the edge effect by evenly distributing the material, which also maximizes the amount of crushed material during the process. The HRC™e HPGR flange rolls bring improved energy efficiency, reduces the circulating load and increased tire life.

The new F-Series HPGR is a successful prospect for Ivrindi Gold

HPGR technology works by exposing the feed material to very high pressure for a short amount of time. This causes the rock to crack and cleave along the grain boundaries, creating a large number of fines but also forming microcracks in the larger particles. These microcracks create 'canals' to the gold ore particles trapped inside the ...

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
