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
