The high pressure comminution process causes micro-cracks in the particles, which lead to the liberation of minerals and a higher portion of fines. HPGR treated minerals show better leaching performance, because the micro-cracks increase the particle contact surface for the leaching liquid. Also, flotation efficiency is further enhanced through ...High Pressure Roll Mill / RHP 16Lab Minerali Engineering. 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
