Cement mill Wikipedia
The smaller grades are occasionally cylindrical ("pebs") rather than spherical. There exists a speed of rotation (the "critical speed") at which the contents of the mill would simply ride over the roof of the mill due to centrifugal action. The critical speed (rpm) is given by: n C = 42.29/ √ d, where d is the internal diameter in metres. Ball mills are normally operated at around 75% of

Ball Mill Critical Speed Mineral Processing & Metallurgy
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 shell’s inside surface and no balls will fall from its position onto the shell. The imagery below helps explain what goes on inside a mill as speed varies. Use our online formula The mill speed is typically defined as the percent of the

speed of rotation. As the dished saw blade increases its speed, the rim gets longer by becoming undished or by “standing up straight.” The process of dishing a saw is called tensioning the saw. It was done mainly by hammering the saw, but is now often done with automatic rollers and tensioning devices. In any case, a large diameter saw must
