The ball mill Chemical Engineering Beyond Discovery
The ball mill is used for the grinding of a wide range of materials, including coal, pigments, and felspar for pottery, and it copes with feed up to about 50 mm in size. The efficiency of grinding increases with the holdup in the mill, until the voids between the balls are filled. Further increase in the quantity then lowers the efficiency.
