What is a Ball Mill?

A ball mill is a grinding device that is used to turn material into fine powder. Ball mills are cylindrical in shape, and are often the grinder of choice when it comes to mashing paints, ores, ceramic materials, and certain hard chemicals. By rotating on a horizontal axis, a ball mill can effectively convert a hard material into a loose powder.
