High Pressure Roll Mill

In a traditional tubular mill, grinding is due to the compression and attrition of the mineral to be milled between the balls (or pebbles) and the drum. RHP high pressure roll mills upsets this principle: the material is forced to pass through two rolls and it's the pressure between the grains which causes the crushing. The results?
