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.
Mixing can be either by internal mixing or external/open mill mixing which have very different safety problems. Internal mixing (eg. Banbury or Intermix mixers) The compound ingredients are fed into an enclosed mixing chamber via a feed hopper and mixed by the shearing action of two winged rotors and the walls of the mixing chamber.
Ball mill operation is often regarded as something of a mystery for several reasons. Ball milling is not an art - it's just physics. The first problem will ball mills is that we cannot see what is occurring in the mill. The other problem is that many of the independent variables .
Opening the ball mill box reveals a user's manual, a mill base, two mill jars, and five extra drive belts. Unpacking the Ball Mill The ball mill jars The first thing that struck me when I first looked at these mills was the nice quality of the mill jars. These things are really heavy-duty, and have a very solid closing and sealing-lid assembly.

In Grinding, selecting (calculate) the correct or optimum ball size that allows for the best and optimum/ideal or target grind size to be achieved by your ball mill is an important thing for a Mineral Processing Engineer AKA Metallurgist to do. Often, the ball used in ball mills is oversize "just in case". Well, this safety factor can cost you much in recovery and/or mill liner wear and tear.
