Ball mill. A typical type of fine grinder is the ball mill.A slightly inclined or horizontal rotating cylinder is partially filled with balls, usually stone or metal, which grind material to the necessary fineness by friction and impact with the tumbling balls. Ball mills normally operate with an approximate ball charge of 30%.

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.

A ball mill is a type of grinder used to grind and blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell.

The plant data and the pebble wear measured in the experiments was used to calculate the flow of pebbles required to maintain a 25% pebble volume in the ball-mills. The average pebble consumption was calculated to be about 5% of the feed to the ball mill circuit. This will

The pebble mills need to be much larger than ball mills, to draw the same power, and hence it is not easy to change from one type of milling to the other. Most mining companies have opted for the ‘safe’ option of ball-mills for secondary grinding.

Pebble mills also known now as ceramic lined mills are a type of ball mill and are used in the size reducing or milling of hard materials such as minerals, glass, advanced ceramics, minerals for ceramics and semiconductor materials down to 1 micron or less.

The feed size for these mills is limited to the maximum size that can be practically conveyed and introduced into the large mill feed chutes. And the product of the large AG/SAG grinding is either a finished size ready of processing, or an immediate size for further grinding in a ball mill, pebble mill, or a VERTIMILL® or a stirred media detritor (SMD).

Both ball and pebble mills work by impact and attrition – a cylinder rotates and moves either balls or pebbles around to grind materials into fine powder. Pebble mills are preferred when working with materials that must avoid iron contamination.

The mill product can either be finished size ready for processing, or an intermediate size ready for final grinding in a rod mill, ball mill or pebble mill. AG/SAG mills can accomplish the same size reduction work as two or three stages of crushing and screening, a rod mill, and some or all of the work of a ball mill.
