HighPressure Grinding RollerPresses - KHD

sizes ranging in grinding force from 2 to 32 meganewtons. The specific grinding pressure is kept below 7.0N/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, raw material or for special applications, such as preparation of ore. To keep wear costs to a .
