nbsp 0183 32 The critical rotation speed of the jar significantly depends on the ball-containing fraction as seen in Fig 3 and is not determined by Eq 1 for given radii of the jar and the ball only The critical rotation speed is close to the value determined by Eq 1 as the ball-containing fraction approaches to one since concentric circles approximately represent the trajectories of balls as the...

Critical speed depends upon the magnitude and location of the shaft unbalance the length of the shaft its diameter and the kind of bearing support Many practical applications suggest as good practice that the maximum operating speed should not exceed 75 of the critical speed however there are cases that require speeds above the critical speed to work correctly...
