Mining companies are now beginning to incorporate HPGR technology and Phelps Dodge (now Freeport-McMoRan Copper & Gold Inc.) is an example of a mining company that has taken the lead in introducing HPGR at Cerro Verde mine in Peru, in 2006.
The Coalition for Energy Efficient Comminution (CEEC) has been established and is supported by a broad range of mining sector companies keen to accelerate awareness, knowledge transfer and, by implication, improve energy and cost outcomes in the substantive area of comminution.
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.
WEIR Minerals KHD crusher High Pressure Grinding Rolls – Crushing and grinding for ore and minerals processing.
