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 ball mill is a tumbling mill that uses steel balls as the grinding media The length of the cylindrical shell is usually 1–15 times the shell diameter Figure 811The feed can be dry with less than 3 moisture to minimize ball coating or slurry containing 20–40 water by weight

Ball mills can be used to further break down or refine a single material or you can place multiple materials into a ball mill jar to mix as you pulverize this is a very common industrial solution for mixing glazes that require the smallest of mesh sizes Ball mills basically function like a mortar and pestle but on a much larger scale

We can calculate the steel charge volume of a ball or rod mill and express it as the of the volume within the liners that is filled with grinding media While the mill is stopped the charge volume can be gotten by measuring the diameter inside the liners and the distance from the top of the charge to the top of the mill The loading or change volume can then be read off the graph below or
