Working principle of high pressure grinding roll: the grinding roll is composed of two extruding rollers, one is fixed roll and the other is movable roll. The material is continuously brought into the roll by the extrusion roller, and after being subjected to high pressure, the material forms compacted cake and is removed from the machine.
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 .
High Pressure Grinding Roll saving energy and providing results. Long wear part life Our HGPRs are specially equipped with durable wear parts that are made to last longer and get more done for you in your operation.

High Pressure Grinding Rolls Outotec''s high pressure grinding rolls are designed and manufactured by Köppern, which has over 100 years of experience in HPGR RD, testing and manufacturing. The HPGR comminution process is based on the introduction of coarse feed material into the preset gap between two counterrotating rolls; a fixed roller and a
High pressure grinding rolls. A high pressure grinding roll, often referred to as HPGRs or roller press, consists out of two rollers with the same dimensions, which are rotating against each other with the same circumferential speed. The special feeding of bulk material through a hopper leads to a material bed between the two rollers.
2 DRIVE YSTEM OR HIGH PRESSURE GRINDING ROLL ROLLXTEND™ Application challenges Today''s highly competitive mining industry calls for continuously operating, high throughput equipment, such as the HPGR, to be designed for maximum availability and reliability. A HPGR''s optimum point of operation is widely influenced
HPGR technology is a qualified alternative for largescale comminution circuits and is becoming ever more popular in minerals processing. The technology''s working principle is that two counterrotating grinding rolls expose a column of material to high pressure, which is distributed across the gap between the rolls.
