  • How HPGRs compare to conventional milling

    The Advantages of Inter-Particle ReductionOffloading (S)Ag Mills Pebble Crushing Via HPGRHPGR Wear vs Conventional MillsOther Points of Comparison Between HPGR and MillsBall, SAG and rod mills all require their grinding media to be regularly replaced, unlike a HPGR. 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 quick exchange system allows for rollers to easily be replaced within
