In 2004, IMS Engineering identified changes in the field of comminution whereby an interesting technology, the High Pressure Grinding Rolls (HPGR) offered substantial metallurgical and other operational benefits in various fields.
by the identification and selection of HPGR technology but also because of the high level of hardness of the rock. This, and the fact that it is a brownfields project, in existence since about 1996, compounded the complexity of the trade-off studies. 10-20% Operational cost savings possible with HPGR technology Global presence and experience 3.
Demand for HPGR technology from the mining sector has been on the up in recent years as companies, especially those in the iron ore game, look to increase the grades of their product to satsify the increasingly 'green' requirements of consumers in China and elsewhere.
The non-conventional HPGR-based circuit brings the capital cost to the level of the traditional SAG-Ball mill circuits. • The innovative HPGR circuit provides similar operational cost savings of the "standard" HPGR and promote the utilization of a technology that enables higher energy efficiency and reduced greenhouse gas emissions.
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.
