HPGR or high-pressure grinding rolls have made broad advances into nonferrous metal mining. The technology is now widely viewed as a primary milling alternative, and there arc a number of large installations commissioned in recent years. After these developments, an HPGR based circuit configuration would often be the base case for certain ore types, such as very hard, abrasive ores. Though ...

HPGR in coarse ore was commissioned at Los Colorados in 1998, there were only 14 HPGRs installed in the minerals industry, mainly for grinding pellet feed to increase the Blaine value [Van der Meer et al., 1997], and only three KHD HPGR units were applied for crushing coarse ore.

Chat3. 4. It has now been several decades since the high-pressure grinding roll (HPGR) made its debut in mineral processing from its cement-based origins. 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 ...
