High Pressure Grinding Rolls 911Metallurgist High Pressure Grinding Roll Features PerformanceHPGR ComminutionOperating Experience with HPGR in The Minerals Industry The high pressure grinding roll has established itself in various industries. High pressure grinding rolls has been leading the way for the use of HPGR in the nonferrous metals mining industry.
Finish grinding Use of the highpressure grinding roll for finish grinding achieves the greatest energy savings, which can be as high as 50%, compared with conventional tube mill systems. Feed material with up to 4% moisture content is dried in the separator. Material with higher moisture contents is dried in a separate unit, for instance a
As grinding plays an essential role in minerals processing, the need for innovation in grinding is critical to circuit optimization. The Outotec HRC e high pressure grinding rolls (HPGR) is combining proven technology with a customerfocused evolution for superior grinding and energy efficiency to help optimize your operations.
2 The highpressure grinding roll has proven to be extremely effective for the grinding of mineral raw materials. With numerous POLYCOM#174; installations in different industrial sectors, ThyssenKrupp Industrial Solutions is the worldwide market leader for this technology.
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.

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. 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.
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#174; roll surfaces 6 #174; polycom highpressure grinding roll 7
