High pressure grinding rolls (HPGR) Metso
High pressuregrinding rolls(HPGR) are used for size reduction or rocks andores.They compress the feed material between two rotatingrollers,one of which is in a fixed position and anotherrollerthat is floating. The two rotatingrollersgenerate such a high pressure that it grinds the feed material to the desired smaller grain size.

March 3, 2020 by frank. TheHPGR (high pressure grindingrolls/rollers) is the core equipment of the high pressuregrindingprocess. The machine reduces 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, exceeding its …
