    Mill Speed An Overview Sciencedirect Topics

    In contrast to conventional tumbling mills, rotational speeds, which determine media collision frequency, are not limited by the onset of centrifugation when the centrifugal force due to rotation of the shell equals or exceeds that of gravity i.e., at the critical speed. As the mill speed increases, the effective gravitational force also increases. Provided the ratio of mill speed to orbital speed falls
