An examination of the literature shows, however, that the actual difference between the results of wet and dry milling are often very large; for example the power to drive a tube mill in which a given material is being wet ground may be as much as 30 % less than that of a similar mill dry grinding. Furthermore the throughput of a continuous ...

A ball mill is a grinder which is used to grind, blend and mix materials like chemicals, ores, pyrotechnics, paints, mineral dressing process, paint and ceramic raw materials. Its working principle is impact and attrition. Ball milling have proved to be effective in increasing solid-state chemical reactivity and production of amorphous materials.
