A Pilot-Scale Examination of a High Pressure Grinding Roll/Stirred Mill Comminution Circuit, in: Autogenous and Semi-autogenous Grinding Technology Conference, Vancouver, 2011. Dundar H., Benzer H., Aydogan N., Application of Population Balance Model to HPGR Crushing, Minerals Engineering, 50–51 (2013) 114–120.
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%."
With our innovatively engineered and proprietary edge, stud and roll design and unique and proprietary state of-the-art wear technology, CSP's high-pressure grinding rolls deliver best in class performance and proven industry leading high wear, extended service life, ease of maintenance and significantly reduced maintenance costs.
