High pressure grinding rolls(HPGR) are used for size reduction or rocks and ores. They compress the feed material between two rotatingrollers, one of which is in a fixed position and anotherrollerthat is floating. The tworotating rollersgenerate such ahigh pressurethat it grinds the feed material to the desired smaller grain size.

PG roller crusheris widely used for fine orsuperfine crushingin the industries of mining, construction materials, metallurgy, chemical industries and so on. It couldcrushall kinds of materials under medium hardness, such as ore, rock, coke, coal, clinker, ceramic raw materials, slag, refractory materials, chemical materials and so on.
ARoll Crusheris massively built; without gears, countershafts, or oil pumps, and with only one moving part. A heavy, annealed, caststeel framesupports the unusually large, accurately finished and polished eccentric shaft, which rotates on heavy duty bearings.
Freeport’s Morenci operation, for example, commissioned a 3.0 x 2.0-m Metso HPGR (called the hydraulic rolls crusher, or HRC) in an expansion mill circuit in 2014. The circuit has a single-line capacity of over 60,000 tpd. with the single HRC having 11.4 MW of installed power, and operating in conjunction with twin MP1250 cone crushers to feed twin 24 x 40-feet ball mills (26 MW for each of installed power).
High Pressure Grinding Rolls (HPGR) In a roll crusher comminution primarily involves individual particles nipped between converging roller surfaces. The forces of compression and friction between the rolls and particles are responsible for size reduction, provided the combined forces exceed the compressive strength of the particle.

Theseroll crushershave large forces of compression and are calledhigh pressuregrinding rolls (HPGR). The present trend is to replace secondary conecrushersby HPGR. The work at Polysius [3] and described by Friedrich and Baum [4] , and Otte [5] indicates considerable metallurgical advantage in the extraction of minerals such as gold and ...
The compressive nature of the HPGR mechanics causes the rock to typically crack and cleave along the grain boundaries, weakening the rock structure and exposing the ore particles. Thishigh pressurealso creates a large number of fines and causes the formation of microcracks in the larger particles.
