Ball Mill Rotating Speed

Once you know the ideal speed of rotation for your mill jars you will need to design your mill around this critical parameter. With most ball mill designs you have two areas of speed reduction to tweak from the motor drive shaft to the drive pulley and from the roller bar to the milling jar.
