How To Calculation Critical Speed Of Sag Mill general the bigger the mill diameter the lower are the mill operating and critical speeds. Thus for larger mills the number of poles will increase. As a result the number of poles can vary from 48 to 72 poles Fig. 3. with typical mill speed requirements of about 10 rpm for larger SAG mills and about 15 rpm for smaller ball mills. Figure 3.
THE ENGINEERING AND PROCESS EFFECTS OF CHOOSING A MOTOR the mill speed as a fraction of the critical speed ϕC can be observed by plotting the process power and torque draw superimposed on the relevant motor capability curve. Such plots for an example mill the SAG mill at Cadia described by Dunne et al. 2001 is shown in Figure 3.
Critical speed of sag mill pdf- Mining Machinery Co. Ltd. Ball Mill Critical Speed Mineral Processing and Metallurgy. A Ball Mill Critical Speed actually ball rod AG or SAG is the speed at which the centrifugal forces equal gravitational forces at the mill shell& 39;s inside surface and no balls will fall from its position onto the shell The imagery below helps explain what goes on inside a mill as speed varies
Critical Speed Ball Mill 2020-7-18A ball mill critical speed actually ball rod ag or sag is the speed at which the centrifugal forces equal gravitational forces at the mill shells inside surface and no balls will fall from its critical speed of a tumbling mill definition of critical speed of a tumbling mill dec 15 2012 critical speed of ball mill .
Low SAG Mill Critical Speed - Grinding and Classifi ion If you have to reduce the SAG mill speed because of avoiding liner breakage maybe it’s better to modify the shell lifter design. Low speed may cause decreasing capacity higher steel ball and liner wear rate. D80 of SAG mill may be finer because of more cascading action and less capacity which results in more retention time in SAG mill.
