AMIT 135: Lesson 7 Ball Mills Circuits – Mining

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.

Industrial Ball Mills for Sale - 911Metallurgist

Ball Mill for Sale. APPROXIMATE CAPACITIES. All ball mills operate on the same principles. One of these principle is that the total weight of the charge in the mill-the sum of the weight of the grinding media, the weight of the material to be ground, and any water in the mill—is a function of the percentage of the volume of the mill it occupies.
