A simple estimation method of materials handling specific energy

Cerro Verde is 95%–110% (Koski et al, 2011) and the fine screen circulating load at Boddington is 80% (Hart et al, 2011). These are rounded off to 100% circulating load (meaning the HPGR feed rate is double the feed rate to the overall circuit). Both operations employ wet screening of fine ore,

Validation of methodologies for sizing a high pressure

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 an HPGR, 2

Predicting HPGR performance and understanding rock

High pressure grinding rolls (HPGR) are becoming an increasingly popular energy efficient solution for comminution of hard rock ores. A significant barrier to the increased adaptation of HPGRs is the current requirement for large amounts of sample for pilot testing. The primary objective of the research was to develop a DEM based computer model for an HPGR to analyze the particle behavior in
