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 […]

With the advent of high-pressure grinding rolls (HPGR) in the 1980's, the comminution process efficiency improved to some extent in terms of energy savings. In HPGR, particle breakage is the result of high inter-particle stresses generated when a bed of solids is compressed moving through the narrow gap created between two pressurized rolls.
