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.
The geometry of a mill with conical ends is shown in Figure The total volume inside the mill is given by Vm 4 D2 mL 1 2(Lc L) L 1 (Dt/Dm) 3 1 Dt/Dm () The density of the charge must account for all of the material in the mill including the media which may be steel balls in a ball mill.
Ball Mills are generally used to grind material 1/4 inch and finer, down to the particle size of 20 to 75 microns. To achieve a reasonable efficiency with ball mills, they must be operated in a closed system, with oversize material continuously being recirculated back into the mill to be reduced.
