Role of feed moisture in high-pressure roll mill ...
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 the feed.
