Pebble Mill Grinding. 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.

Tube Mills consist of revolving cylinders, the interior of which is perfectly plain. They contain a number of hard balls. They differ from ball mills essentially in having the inlet for ore at one end and the outlet at the other, and in the absence of provision in the machine itself for the return of uncrushed material (oversize).
