Metallurgical ContentTube Mill CapacityPebble Mill CapacityPEBBLE MILL LINERSPEBBLE MILL GRINDING MEDIA Essentially tube mills and pebble mills may be considered as ball mills, the basic difference being that the ratio of length to diameter is greater. Usually the shell length is between 2 and 5 times the diameter. These mills are primarily used to grind various materials to 100 mesh and finer.

In a planetary mill, the energy transfer is essentially governed by the hit of the ball against the vial wall. In order to analyse the hit mechanism, the velocities of the balls inside the mill have been estimated and reproduced in "free fall" experiments, in which the yield of the impact has been measured.

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.
