Ball Mills vs Rod Mills 911 Metallurgist

2017-7-3  Stage grinding which is by repeated passes followed by removal of the finished material, is the best means of obtaining selective grinding. These terms must not be confused with differential grinding, which has to do with the relative grinding rates of two or more minerals in an ore. Rod Mills = Selective Grinding. Ball Mills = Non-Selective Grinding
