Online servicesBall mills have been successfully run at speeds between60and90 percentof critical speed, but most mills operate at speeds between65and79 percentof critical speed. Rod mills speed should be limited to a maximum of70% of critical speed and preferably should be in the60 to 68 percentcritical speed range.
Aug 23, 2018·CRITICAL SPEEDOF THEBALL MILL. Let a grindingball of massm is in motion in amillof diameter D meters. It is at a position making an angle a at the center (called the angle of repose). The force acting on theballaredescribedin the figure. The centripetal force acting along C. The force of gravity due to its weight along G.
