High Pressure Grinding Rolls are generally thought to only be effective in controlled "dry" grinding applications, however (depending on the material saturation level) they can readily process minerals well above 10% moisture. This gives HPGR's the flexibility to fit into a wide array of applications with both wet and dry classification.Web

The HPGR (high pressure grinding rolls/rollers) is the core equipment of the high pressure 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 …Web
