HPGR High Pressure Grinding Rolls Weir

With their excellent throughput capacity, low maintenance requirements and energy efficiency, HPGRs are fast becoming the go-to technology for greenfield projects. 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.
