Grinding media can be the ore itself (autogenous grinding -- primary and secondary), natural or manufactured non-metallic media (pebble milling) or manufactured metallic media -- steel rods, steel or iron balls. This chapter will discuss general mill design and the specific design and application of the following types of tumbling grinding mills.

A Ball Mill Critical Speed (actually ball, rod, AG or SAG) is the speed at which the centrifugal forces equal gravitational forces at the mill shell's inside surface and no balls will fall from its position onto the shell. The imagery below helps explain what goes on inside a mill as speed varies. Use our online formula The mill speed is typically defined as the percent of the Theoretical ...

A better way of polishing stones is to use a Tumbling machine (also known as a tumble polisher, rock tumbler, pebble polisher or stone tumbler); these are small electrical units, using silicon carbide grit as mentioned above. Rough stones, of equal hardness, are put in a barrel with water and grit and the barrel is slowly rotated.

Size Reduction. Tumbling Steel Ball Mills and Ceramic Lined Mills are one of the most precise, reliable and cost effective methods of fine grinding solids in either a wet or dry state.Ball Mills are referred to by many names including Pebble Mills, Tube Mills and Attrition Mills, but no matter what the nomenclature they all operate on the same efficient principle.

A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls; mounted on a metallic frame such that it can be rotated along its longitudinal axis. The balls which could be of different diameter occupy 30 – 50 % of the mill volume and its size depends on the feed and mill size.
