To reduce In terms of energy consumption, the so-called good bed roller mill has been developed. The High pressure grinding roll has two opposite directions rotating rollers forming a nip between them, in which the ground material is drawn in and comminuted under high pressure becomes.

and mining sector, roll bodies with surfaces protected against wear by hard metal studs are generally used. Material Operating hours Iron ore pellet feed up to 60,000 h Hard rock applications up to 20,000 h Lifetime hours actually achieved by polycom® roll surfaces 6 ® polycom high-pressure grinding roll 7

The high pressure grinding roll machine comprises a pair of counter-rotating rolls mounted in a sturdy frame. One roll is fixed in the frame, while the other is allowed to float on rails and is positioned using pneumo-hydraulic springs. The feed is introduced to the gap between the rolls and is crushed by the mechanism of interparticle breakage.

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.

HPGR or high-pressure grinding rolls have made broad advances into nonferrous metal mining. The technology is now widely viewed as a primary milling alternative, and there arc a number of large installations commissioned in recent years. After these developments, an HPGR based circuit configuration would often be the base case for certain ore types, such as very hard, abrasive ores. .

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 grain size.
