Ball Mill Critical Speed Mineral Processing Metallurgy. Ball mills have been successfully run at speeds between 60 and 90 percent of critical speed but most mills operate at speeds between 65 and 79 percent of critical speed Rod mills speed should be limited to a maximum of 70 of critical speed and preferably should be in the 60 to 68 percent critical speed range

Results showed that the milling ball load and mill speed have greater influence on the energy efficiency than the charged material volume [17]. A similar work carried out on a pilot mill showed ...
