  • 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. The first problem will ball mills is that we cannot see what is occurring in the mill. The other problem is that many of the independent 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.
