RHP is an high pressure roll mill: unlike a coventional roll mill, the compression of the material against the rolls allows the fine grinding, not a simple lamination. "Auto-comminution allows the transformation of about 50% of the supplied energy into usefulenergy for grinding. In a tubular mill this value is only 20%."

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.

The main factors affecting rolling pressure are: (1) Absolute rolling reduction. When the roll diameter and the friction coefficient are the same, with the increase of the absolute rolling reduction, the contact area between the rolled piece and the mill roll increases, and the rolling pressure increases.
