How does a High Pressure Grinding Rolls (HPGR) works

Dec 29, 2012· How does a High Pressure Grinding Rolls (HPGR) works

With a number of hard-rock mining applications in large concentrators now several years into production, the time has come to break away from the concept of simply using HPGR in minerals applications, and instead to start focusing on further developmental paths that lie ahead as the technology is optimised specifically for the hard-rock mining.

Not another HPGR trade-off study!

Abstract Over the past several years, the combination of higher energy and steel costs and the recent commercial deployment of high-pressure grinding rolls (HPGR) technology in hard rock mining have led many multinational mining companies to evaluate the suitability of HPGR technology for their particular comminution circuits.
