High pressure grinding rolls (HPGR) liming

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.

More efficient grinding for Iron Range industries

03/06/2020· Unlike rod or ball mills, high pressure grinding rolls 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. There are no rods or balls that need replacing and it reduces energy consumption by about 40 percent for certain ore types. It also substantially reduces water
