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

pressure gradient across the width of the roll and the static confinement of the ore at the edges of the rolls which the cheek-plates provide. High pressure rolls: bed breakage Edge effect: particles broken in a way similar to that in a conventional rolls crusher Figure 5: Schematic of the Edge Effect Zone iii.

Köppern – Specialists in High-Pressure Comminution 7 Improved Cost-Efficiency High-pressure grinding roll presses (HPGRs) are emerging as an important comminution technology in the minerals processing industry. The technology has found its key application in the liberation of diamonds and also in primary comminution.

The technology's working principle is that two counter-rotating grinding rolls expose a column of material to high pressure, which is distributed across the gap between the rolls. Interparticle comminution is the HPGR specific grinding process in which material particles are crushed and ground within the compressed material bed and not by contact with the roll surface.
