The ball mill is a key piece of equipment for grinding crushed materials, and it is widely used in production lines for powders such as cement, silicates, refractory material, fertilizer, glass ceramics, etc. as well as for ore dressing of both ferrous and nonferrous metals. The ball mill can grind various ores and other materials either wet or dry.

It seems, therefore, that the literature accumulated during the last 20 years, which attempts to elucidate the principles of ball milling by discoursing on balls thrown in the air, is not comprehensive. In a given time, the batch mill, with about 75 pounds of ore charge, did more grinding than the mill with a lighter or heavier ore charge.
