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. The Tube Mill uses iron or steel balls as the grinding media, and liners of various metals and alloys.

The name “ball” or “pebble” refers to the type of grinding media that is introduced into the mill. The media when combined with ores or other subtances accelerate particle size reduction by virtue of their impacting on the particles as the mill rotates. The grinding action is as described in our article about how grinding mills work

A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints. Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles

Since the weight of pebbles per unit volume is 35–55% of that of steel balls, and as the power input is directly proportional to the volume weight of the grinding medium, the power input and capacity of pebble mills are correspondingly lower. Thus, in a given grinding circuit, for a certain feed rate, a pebble mill would be much larger than a ball mill, with correspondingly a higher capital
