It's better to antimony-hardened 1/2-inch diameter lead balls, made specifically for pyrotechnic ball milling. They cost a little more than the soft, pure lead balls, but last much longer. 5 pounds (200) 1/2-inch balls will fill one of these jars half full, which is exactly what you want.
Experience Counts. Moly-Cop has been manufacturing grinding balls since the 1920's. With ten manufacturing sites strategically located in key mining regions, we have flexibility and product quality to meet the needs of modern milling operations.
A ball mill is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints. Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls and steel balls.
I wonder if its possible to use the bearing balls in ball milling system. The material for grinding is charcoal and there is no problem with the hardness.
1. Chemical compatibility. Is the grinding media going to introduce any chemical contamination issues? All grinding media will contaminate the product being ground to some extent or another even if the contamination is in the ppm or ppb range, so it's important to consider what's acceptable and what isn't.
