Enduron® HPGR - The Weir Group

Feb 02, 2021· HPGRs are highly effective for heap leaching because the high pressure particles experience between the HPGR's tyres introduces 'micro-cracks' or fractures, which allow the leaching chemicals to effectively diffuse through the particles and liberate the gold ore. Research has indicated this can provide up to 10-11% additional gold ...

High pressure grinding rolls (HPGR) - Outotec

High pressure grinding rolls (HPGR) are used for size reduction or rocks and ores. They compress the feed material between two rotating rollers, one of which is in a fixed position and another roller that is floating. The two rotating rollers generate such a high pressure that it grinds the feed material to the desired smaller grain size.
