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

2016-11-18  The critical speed must be known in order to calculate the optimum speed, which is the speed that you actually want your jar to rotate at. The optimum speed varies as a percentage of the critical speed depending on the viscosity of the material being ground. For the dry powders used in pyrotechnics, the optimum speed will be 65% of the

What it is the optimun speed for a ball mill

2006-10-19  Posted 21 October 2006 04:24 PM. Congratulations on your ball mill! You'll want to further reduce your motor speed by 3:1 to mill more efficiently. Right now, your RPM is just slightly under the speed where the media won't do any work. The optimum speed for your jar to turn is around 90 RPM like Frozentech said.
