Metso and Freeport-McMoRan celebrated an impressive milestone in Q2, 2017 as the new HRCTM3000, the world’s largest operating high-pressure grinding roll, at the Metcalf concentrator crushed its 100 millionth short ton of ore.
Reaching 100 million short tons of crushed ore is a significant milestone for the world’s largest operating high-pressure grinding roll (HPGR). Due to its capacity, the HRC3000 reached this milestone in less than three years. It began operating in May 2014 at the Metcalf concentrator at Freeport-McMoRan’s copper mine in Morenci, Arizona, USA. Morenci is an open-pit copper mining complex that has been in continuous operation since 1939.
The HRC3000 is the largest unit of its kind in the world, allowing for fewer lines of equipment which reduces the amount of ancillary equipment. The HRC3000 is the first full-scale HPGR to incorporate revolutionary design features such as the flanged tyre design and the patented Arch-frame. Metso’s solution has provided the Morenci mine with several benefits, including an estimated 13.5% increase in energy efficiency over traditional HPGRs based on pilot scale testing.
