High pressure grinding rolls (HPGR) - Outotec
Robust HRC™ high pressure grinding rolls (HPGR) 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 ...

At the Polysius Research Centre Atwal wear (HPGR with 100 mm roll diameter) and Regro (HPGR with 720 mm roll diameter) reliability tests were conducted. The results of these test indicated that Platreef ore is very amenable to HPGR comminution, having high specific throughput rates, creating high percentage of fines (29–33% passing 250 μm)

The uptake of HPGR technology by metallic mineral processors has involved a number of suppliers but primarily KHD Humboldt Wedag and Polysius for the HPGR machines and ABB for the drive systems. Normally, it is the HPGR supplier's prerogative to choose the drive supplier; the end user normally buys the HPGR with the drive systems included.

HPGR High Pressure Grinding Rolls |
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 ...
