Ball Mill Operating Speed Mechanical Operations Solved

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, n c = 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.

Critical rotation speed for ball-milling ScienceDirect

Aug 03, 1999 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
