    rod mill design calculation 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 shells 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.

    actually breaking the particles. 1.1.1. T h e motion of the charge in a Tumbling Mill Due to the rotation and friction of the mill shell the grinding medium is lifted along the rising side of the mill until a position of dynamic equilibrium is reached. The grinding medium can be steel rods or steel balls. At that stage the bodies cascade and cataract down the free surface of the other bodies
