 · 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.

 · Large mill (D>5.0 m (16.5 ft)) performance has been successfully predicted from small scale batch experiment for grinding kinetics and an RTD correlation for transport using population balance models.The effect of ball size must be properly taken into account in the scale-up.

2  · The design of ball end mills forms a hemispherical cutting action identical to the diameter of the tool. Because of the shapes required in these products it's common that multi axis machining centers are used for this work. They can also be used in a secondary way to form a radius at the juncture of perpendicular surfaces.
