HPGR

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 []

High Pressure Grinding Roll

7) High Efficiency The high-pressure grinding roll applies the principle of laminated crushing, which is an efficient compressive stress crushing. The crushing efficiency is significantly higher than the ball milling crushing dominated by compressive stress and shear stress, so the energy consumption of the equipment is low. 8) Economic Cost
