Critical speed WikipediaMill Critical Speed Formula Derivation Grinding
In solid mechanics in the field of rotordynamics the critical speed is the theoretical angular velocity that excites the natural frequency of a rotating object such as a shaft propeller leadscrew or gearWhen 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
