Mill Critical Speed Formula Derivation

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 = 42305 /sqt(D-d) N c = critical speed of ....
