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, exceeding its ...

The high-pressure grinding roll (HPGR) is emerging as an important comminution technology in the minerals processing industry. In direct competition with grinding by semi-autogenous tumbling mills (SAG) and ball mills (BM), the technology has found its key application in primary comminution and also in the liberation of diamonds.

as high pressure homogenizers, bead mills or rotor/stator systems. Enhanced pressure range The precise and powerful roller pressure unit generates linear loads from 5 to 90 N/mm (VIVA rolls) or 5 to 120 N/mm (P-rolls). Compared to conventional three-roll mills this range is signifi-cant wider for both low and high roller pressure. Products,
