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. If 100 mm dia balls are replaced by 50 mm dia balls, and the other conditions ...

Critical Rotational Speed Nc Of Ball Mill. Critical speed of ball mill - SBM. The speed of rotation rpm of the loaded ball mill is critical to success too slow, and the milling takes too long while too fast, and the contents balls, ore and water slam against the wall, inhibiting milling.

Example: a mill measuring 11'0" diameter inside of new shell liners operates at 17.3 rpm. Critical speed is C.S. = 76.63 / 11^0.5 = 23.1 rpm Ball and SAG Mills are driven in practice at a speed corresponding to 60-81% of the critical speed, the choice of speed being influenced by economical considerations.
