High pressure grinding rolls (HPGR) are used for size reduction or rocks and ores. They compress the feed material between two rotating rollers, one of which is in a fixed position and another roller that is floating. The two rotating rollers generate such a high pressure that it grinds the feed material to the desired smaller stone size.

High-pressure comminution process research is a fundamental element of process design in the mining industry. Köppern has several semi-industrial sized pilot-plant facilities currently installed at the Bergakademie Freiberg, the University of British Columbia and also at research institutions High-pressure grinding roll presses (HPGRs) are
The high-pressure grinding roller press (HPGR) is centered around two counter-rotating rollers. These are supported in the frame by spherical roller bearings that are inherently self-aligning and extremely robust. In addition to radial loads, the bearings are able to accommodate axial loads in
HPGR technology is a qualified alternative for large-scale comminution circuits and is becoming ever more popular in minerals processing. 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.
"The increasing adoption of HPGR in the mining and cement industry is expected to propel the market growth" The global High Pressure Grinding Roller (HPGR) market is anticipated to witness a robust growth owing to the increase in the adoption of the mining and cement industry.
