Rotation of ball mill at critical speed
06/08/2015 · If speed of rotation is low, it results in insignificant milling action as balls only move in lower part of the drum. If speed of rotation is very high, the balls cling to the drum walls due to centrifugal force. Therefore, intense grinding action is obtained only when drum rotates at critical speed and here the ball mill rotates at a speed ...

03/08/1999 · Critical rotation speed of dry ballmill was studied by experiments and by numerical simulation using Discrete Element Method (DEM). The results carried out by both methods showed good agreement. It has been commonly accepted that the critical rotation speed is a function of a ball radius and a jar diameter. The results of the present work, however, show that the critical rotation speed ...
