Metso provides an innovative energy efficient solution with the world’s largest high-pressure grinding roll -The HRC(TM)3000 equipped with impressive range of industry-leading features, aimed at harnessing more value from every ton of ore.
The HRC(TM)3000 was built in collaboration between Metso and Freeport-McMoRan Inc. The goal was to develop a highly efficient HPGR crushing circuit for the newly constructed Metcalf concentrator at Freeport-McMoRan’s copper mine in Morenci, Arizona.
The HRC(TM) 3000 started operating at Freeport-McMoRan’s copper mine in May 2014. The installed unit is the largest of its kind in the world, allowing for fewer lines of equipment which reduces the amount of ancillary equipment. To date, the unit has operated for over 8,400 hours and has crushed more than 34 million tons of porphyry copper ore. Metso’s solution has contributed to an estimated 13.5% increase in energy efficiency over traditional HPGRs based on pilot scale testing.
The HRC(TM)3000 is the first full scale HPGR to incorporate revolutionary design features such as flanged tire design and the patented Arch-frame and its total capacity can exceed over 5,400 tph of ore.
