:: Record Metso HPGR Proving Worth at Morenci


Energy efficiency is the key to success at modern mines and quarries. The most potential for energy and cost savings can be realised in the comminution process, where ore is ground and crushed into smaller particles. With the HRC3000, the largest fully operating high-pressure grinding roll (HPGR) in the world, Metso says it provides "an energy efficient solution with an impressive range of industry-leading features, aimed at getting more value from every tonne of ore."

The HRC3000 was the result of a close 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. In approximately four years, the team went from a design concept to the largest fully operating HPGR in the world.
