The breakage of particles depends on the speed of rotation. Working with a 7.32 m diameter and 3.66 m long mill, Napier-Munn et al. [4] observed that the breakage rate for the finer size fractions of ore (say 0.1 mm) at lower speeds (e.g., 55% of the critical speed) was higher than that observed at higher speeds (e.g., 70% of the critical speed

2020-10-19 The critical speed is the same as the frequency of traverse vibrations. The critical speed N c of a shaft is simply . Where m = the mass of the shaft assumed concentrated at single point . k is the stiffness of the shaft to traverse vibrations. For a horizontal shaft this can be expressed as .
