Critical rotation speed for ball millingScienceDirect. Aug 03 1999 Critical rotation speed of dry ball mill was studied by experiments and by numerical simulation using Discrete Element Method DEM The results carried out by both methods showed good agreement It has been commonly accepted that the critical rotation speed is a function of a ball radius and a jar diameter.

Ball Mill Critical Speed. 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. Details >

Ball Mill Critical Speed. 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’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. Use our online formula.
