TECHNICAL NOTES 8 GRINDING R. P. King - Mineral Tech

The center of gravity first starts to shift to the left as the speed of rotation increases but as critical speed is reached the center of gravity moves towards the center of the mill as more and more of the material is held against the shell throughout the cycle. Since critical speed is larger at smaller radii the centrifuging layer gets

Effects of rotational direction and rotation-to-revolution ...

This critical speed ratio, r C, can be derived by taking the equilibrium of centrifugal force acting on the ball during milling from the rotation of the pot and the revolution of the disk, as follows: two centrifugal forces (F p: rotation, F r: revolution) are derived from, .

Ball Mills - Mine Engineer.Com

The point where the mill becomes a centrifuge is called the "Critical Speed", and ball mills usually operate at 65% to 75% of the critical speed. Ball Mills are generally used to grind material 1/4 inch and finer, down to the particle size of 20 to 75 microns.
