Ball mills are the most effective laboratory mills for rapid batchwise comminution of mediumhard, soft, brittle, fibrous, temperaturesensitive and moist samples down to the finest particle size the comminution of the material to be ground takes place through impact and friction between the grinding balls and the inside wall of the grinding
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 of the mill volume and its size depends on the feed and mill size
By contrast, attrition milling relies on a horizontal rotating vessel filled with a sizereduction solution treated to grinding media, the materials tend to be turned into freeflowing, spherical particles this method, which includes the ball mill, can reduce , micron mesh particles of friable materials down to less than micron
