High Pressure Roll Mill / RHP 16Lab Minerali industriali

2018-7-17  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%.”.
