  • High Pressure Roll Mill / RHP 16Lab Minerali industriali

      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 “Autocomminution allows the transformation of about 50% of the supplied energy into usefulenergy for grinding In a tubular mill this value is only 20%”
