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.

Design considerations for large diameter ball mills

Abstract. Such a correlation is needed for the scale-up design of large ball mills. In order to accomplish such a correlation we analyzed not only our own RTD data, but also the data of others. The data includes mill diameters ranging from 0.4 to 5.5 m (1.3 to 15 ft) and lengths ranging from 0.4 to 9.8 m.
