ball mill, a type of crusher, is a cylindrical device used to grind chemicals or mix compositions. ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium, ideally non sparking milling media like lead balls. An internal cascading effect reduces the material to a fine powder.
