Tumbling Mills Critical Speed

  • Design and analysis of ball mill inlet chute for roller

    Mill liner thickness = 40mm = 0.04m Mill speed = 77% of the critical speed Critical speed (Nc) is the speed at which the centrifugal force is equal to the gravitational force. Nc = 42.3 /D1/2 D is the effective diameter of mill = Mill diameter – Liner thickness = 4.6 – (0.04x2) = 4.52m Nc = 42.3 / 4.521/2 = 19.89 rpm Mill speed = 0.77 x 19
