Get PriceRose 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 .

Cited by: 64Get PriceThe Critical Speed is used for the determination of ball mill ideal operating speed. But for comparison, rod mills would operate between 50% to 95% of the critical speed. The faster the mill speed, the greater the wear on the rods and liners. So, the general rule of thumb for rod mills is to operate no faster than the speed that will obtain the ...
