Ball Mill: Operating principles, components, Uses ...

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.


HOSOKAWAMICRON CORPORATION

Ball mills are giant drums that are filled to between 30 and 40% of their volume with freely moving grinding media – in this case balls. The diameter of the balls is between one and several centimeters to suit the application – smaller pearls for fine grinding results and larger ones for coarser grinding tasks.

Can I use a rock tumbler as a ball mill? – handlebar ...

Ball mills work by using balls to grind materials. Materials such as iron ore, pain and ceramics are added to the ball mill. As the ball bill rotates, the balls bounce around while striking the enclosed material. The force of these strikes helps to grind the material into a finer, less-coarse medium. What is one of the disadvantages of ball ...
