High Pressure Grinding Roller Presses KHD

High Pressure Grinding KHD Humboldt Wedag Roller Presses With our Roller Presses, the grinding pressure is transferred from the hydraulic system via the movable roll to the material bed and absorbed in a stable, closed machine frame A key feature is the mounting of the rollers in oillubricated cylindrical roller bearings The oil is both, lubricant and cooling agent Alternatively, grease lubricationUsed in mining applications for the last 30 years, high pressure grinding rolls (HPGR) reduce particles by compressing and crushing the feed between two counter rotating, parallel rollers with aHPGR High Pressure Grinding Rolls | WeirThe KHD Humboldt Wedag Roller Press is available in ten standard sizes ranging in grinding force from 2 to 32 meganewtons The specific grinding pressure is kept below 70N/mm2 in order to limit the stress on the rollers (grinding pressure = grinding force/roll diameter/roll width) The pressure between the rolls can be lower for grinding granulated slag, rawHighPressure Grinding RollerPresses
