Variables in Ball Mill Operation Paul O. Abbe®
Ball milling is one of the few unit operation that improves with increasing mill diameter. If acceptable results can be obtained with a 12" jar mil then good result will certainly be obtained with a 72" diameter mill. Of course there is the possibility of over milling obtaining a different particle size distribution or a need to change

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.
