• What Is a Ball Mill? - Monroe

    Mar 10, 2020  How 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 ...

    Attritors, wet grind Attritors, regular speed Attritors, and high speed Attritors. A useful and simple equation describing the grinding momentum is M x V (mass x velocity), which enables us to see how the Attritor fits into the family of mills. For example, ball mills use large media, normally 1/2” or larger, and run at a low (10-50) rpm.
