Critical rotation speed for ball-milling - ScienceDirect

Rose and Sullivan showed critical rotation speed N c, to reach the final stage, i.e., centrifugal motion: (1) N c = 1 2π 2g D−2r where D is the inner diameter of a jar and r is the radius of balls. All throughout, they used the critical rotation speed as the constant value for given conditions of ball-mill .
