  • Mill Critical Speed Formula Derivation Grinding

    When the ball mill rotates at the critical speed the theoretical trajectory of the charge is such that it would fall outside the shell as centrifuging occur at this stage and the medium is carried around in a fixed position against the shell. The formula to calculate critical speed is given below. N c = 42.305 /sqt(D d) N c = critical speed of the mill.

  • Ball Mill Operating Speed Mechanical Operations Solved

    Calculations The critical speed of ball mill is given by, where R = radius of ball mill; r = radius of ball. For R = 1000 mm and r = 50 mm, nc = 30.7 rpm. But the mill is operated at a speed of 15 rpm. Therefore, the mill is operated at 100 x 15/30.7 = 48.86 % of critical speed.
