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 The mill speed is typically defined as the percent of the Theoretical ...
Mar 01, 2005· A tumbling mill, whether it be autogenous, semi-autogenous, ball or rod, is a system composed of a number of interrelated and interactive elements that work together in order to grind a given ore. This grinding, or comminution, process is achieved by individual balls that constitute the actual ball mill element which brings about ore breakage.
