How HPGRs compare to conventional milling

Within comminution circuits, High Pressure Grinding Rolls (HPGR) are increasingly replacing conventional SAG, rod and ball mills for hard rock reduction owing to their substantially lower energy consumption and potential for significant total cost of ownership reduction. Not only do they require as much as 40% less energy than traditional reduction methods, but their wearable components

Particle weakening in high-pressure roll grinding

2005-6-1  1. Introduction. High-pressure roll grinding has achieved considerable popularity over the last several years given its potential of improving capacity and reducing energy consumption in a grinding circuit (Schönert, 1988, Fuerstenau et al., 1995, Norgate and Weller, 1994).Comminution in the high-pressure grinding roll (HPGR) is the result of the high interparticle stresses generated when a

HPGR comminution for optimization of copper

High-pressure grinding rolls (HPGR) are an accepted, but continuously expanding, comminution technology. The copper industry has a growing need to process harder ores with progressively lower grades, more challenging metallurgy and increasing demand for efficient bacterial leaching applications. This has resulted in a major focus on HPGR use in a crushing circuit.
