Metso HRC™3000 is a new generation high-pressure grinding roll that eliminates issues found in traditional HPGRs, allowing the mining industry to reach a new level of energy efficiency. The world's largest HPGR was installed at Freeport-McMoRan’s Morenci site in Arizona, USA.
Grinding of material in HPGRs has proven to be more cost efficient as compared to conventional mills and crushers. Especially downstream processing stages such as ball-milling are more energy-efficient due to the finer product size distribution coming out of the HPGR and the additional effect of micro cracks in the HPGR product particles.
Grinding in small plants, as in larger installations, has proven to be the most costly of all unit operations from both capital and operating standpoints. Therefore, grinding deserves the most scrutiny of all operations during the design procedure. A recent survey by a major grinding mill manufacturer reveals that more than 80 autogenous or semi-autogenous mills having between 100 and 1,000
