high pressure dodle roll mill
RHP (High Pressure Roll Mill) RHP is a dry milling machine (maximum moisture 1%). Main components are the two grinding rolls and the compression screws. 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.

Role of feed moisture in high-pressure roll mill comminution
The high-pressure roll mill, HPRM, is an example of continuous grinding under the confined particle–bed mode (Kellerwessel, 1990, Fuerstenau and Kapur, 1995). However, a completely confined particle–bed mode of grinding is difficult to attain in the HPRM because of the well-known end effects that invariably result in some leakage of …
