  • Developments in HPGR technology Mining Magazine

    Mechanical DevelopmentsProcess ConsiderationsOutlookSize of unitsHPGRs in today’s minerals applications commonly feature studded rolls with a diameter of 2.4m. One unit this size can typically be used for a 30,000t/d plant. Larger plants would then typically require two, or more, lines. HPGRs are now availe based on current technology with roll diameters of up to 3m, a siDesign of unitsSince the initial design of HPGRs for minerals applications, the units have grown steadily larger. While the details of the design have been improved, the basic design principles remain essentially unchanged. Recent innovations are making their way into the market with the goal to: 1. Improve the efficiency of HWear surfaceWear-protection concepts that had proven to be successful in the cement industry ultimately failed in most minerals applications, with few exceptions. Without question, the wear-protection system of HPGRs has been the most critical element in attaining successful application in the field of hard-rock mining. Th在miningmagazine上查看更多信息
