Variables in Ball Mill Operation Paul O. Abbe®
Ball mill operation is often regarded as something of a mystery for several reasons. Ball milling is not an art it’s just physics. Mill Speed is one variable that can often be easily changed with a variable frequency drive (VFD). The starting point for mill speed calculations is the critical speed. Critical speed (CS) is the speed at

AMIT 135: Lesson 7 Ball Mills & Circuits Mining Mill
Ball Mill Operation. Ball mills ride on steel tires or supported on both ends by trunnions. Girth gears bolted to the shell drive the mill through a pinion shaft from a prime mover drive. The prime movers are usually synchronized motors. During rotation, a portion of the charge is lifted along the inside perimeter.
