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.
Introduction to Ball Mills. Ball Mills provide the most reliable method of fine grinding all solids down as far as < 1 µ. Depending on their size, materials of construction and design, Ball Mills are referred to by many names including Tumbling Mills, Tubular Mills, Ball Mills, Pebble Mills and Jar Mills, but no matter what the nomenclature, they all operate on the same principle.
