This stone unifies high-pressure grinding rolls crusher (HPGR) models of the working gap, mass flow rate, power draw, and centre and edge product particle size distribution models to produce a framework that allows the simulation of the equipment for process optimization and control studies.
Improved characterisation of ball milling energy
2018115 Abstract. This stone describes a method for assessing the downstream milling energy requirements for high pressure grinding rolls (HPGR) products based on a Bond mill test procedure. Multiple trade-off studies have reported the performance of HPGR versus SAG milling with energy savings of between 11 and 32 per cent.

202151 High-pressure grinding rolls reached great popularity for pressing iron ore concentrates since its first application in the 1990s. For this particular application, mathematical models describing HPGR performance on the basis of operating conditions and feed characteristics have successfully been used by the authors to map industrial
How HPGRs compare to conventional milling Weir
High Pressure Grinding Rolls have lower maintenance overheads than ball and rod mills, primarily because the grinding media in conventional mills needs to be replaced on a more regular basis. This makes HPGRs more flexible when it comes to meeting your campaign timings. When tyres do wear down and need to be replaced, the Enduron® HPGR’s
