Pure lead balls are very soft and will literally grind themselves down to nothing. Our balls are an alloy of several metals and lead which makes them harder than virtually any other lead milling media on the market. A 5-pound (200 ea.) box of these balls is exactly the quantity needed for our 6-Pound Ball Mill (#TL5004).

Ball Mill Overview. A ball mill is a type of grinding machine that uses balls to crush and grind material. The ball mill is made up of a cylinder called the mill shell that turns on a horizontal axis. The mill is filled to a certain filling degree with balls and the mill shell is protected by liners. The materials to be reduced in size are ...

The ball milling process is carried out for approximately 100–150 h to obtain uniform-sized fine powder. In high-energy ball milling, vacuum or a specific gaseous atmosphere is maintained inside the chamber. High-energy mills are classified into attrition ball mills, planetary ball mills, vibrating ball mills, and low-energy tumbling mills.
