High pressure grinding rolls are preferred for their energy efficiency and flexibility in ore processing.
Metso’s unique take on this technology, the HRC HPGR, delivers even bigger – as the most advanced high pressure grinding roll on the market.
HPGRs utilize two counter-rotating tires – 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.
