High pressure grinding rolls(HPGR) introduction

The HPGR (high pressure grinding rolls/rollers) is the core equipment of the grinding process.

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 compressive strength with equal pressure being applied to particles of all sizes.

It first used in the cement industry, while nowadays, also have been used in many other industries like nonferrous metal processing, ferrous metal processing, precious metal processing, etc.
