HRCTMHigh Pressure Grinding Roll (HPGR) has been acclaimed as one of the most energy efficient mining solution when used in the right application. The design is energy efficient due to the basic operating principle whereby the rotating rolls compress the feed and achieve breakage through inter particle compaction. The Metso HRC takes HPGR technology to the next level by providing a simple design that offers increased availability, component longevity, ease of maintenance, circuit capacity and safety.
|HPGRs utilize two counter-rotating tire – one fixed and one floating – in order to effectively crush ore. Hydraulic cylinders apply very high pressure to the system, causing inter-particle comminution as the feed travels between the two tires.|
The basic operating principle behind HPGRs makes them very energy efficient:
The feed is introduced to the crushing zone, where high pressure is applied to the bed of material in a highly controlled manner
