Currently, there is no standard recognized bench-scale laboratory test for sizing or modelling a high pressure grinding roll (HPGR) in hard rock mining. As a result, metallurgical studies are prohibitively expensive and not economical for early-stage projects. To be adopted as a standard industry test for the HPGR, a bench scale test must: 1) use the same breakage mechanism as …
The high pressure grinding rolls is one of the few new comminution devices that offer substantial savings when compared with traditional crushing and grinding circuits and with SAG milling. The machine has been well accepted in the cement industry, but mining companies have been more cautious in adopting this technology, partly because of wear and availability …
