Mar 10, 2020nbsp018332How a Ball Mill Works. Ball mills work by using balls to grind materials. Materials such as iron ore, pain and ceramics are added to the ball mill. Next, the ball mill is activated so that it rotates either on its vertical or horizontal axis. As the ball bill rotates, the balls bounce around while striking the enclosed material. The force ...
