2.2 Rotation Speed Calculation of Ball Mill Critical Speed When the ball mill cylinder is rotated, there is no relative slip between the grinding medium and the cylinder wall, and it just starts to run in a state of rotation with the cylinder of the mill. This instantaneous speed of the mill is as follows
Read MoreBall Mill Critical Speed - Mineral Processing . 2021-3-10 A Ball Mill Critical Speed actually ball, rod, AG or SAG is the speed at which the centrifugal forces equal gravitational forces at the mill shells inside surface and no balls will fall from its position onto the shell.
Read MoreThe 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 14 inch and finer, down to the particle size of 20 to 75 microns.

Read MoreBall Mill . Ball Mills have been successfully run at speeds between 60 and 90 percent of critical speed However most Ball Mills operate at speeds between 65 and 75 percent of critical speed The larger the diameter the slower the rotation If the peripheral speed of the mill is too great it begins to act like a centrifuge and the balls do not fall back but stay on the perimeter of the mill A Ball
