Ball Mill Critical Speed - Mineral Processing Metallurgy

2015-6-19  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 Theoretical ...

When choosing the right parameters to run, most people focus on the speed which relates to the machine RPM. This is a mistake! Focus on on the proper feed per tooth (FPT), and then adjust the speed. Often when a part is programmed, and is being proven out for production, the programmer will choose conservative parameters and encounter chatter.
