Powder Metal Processing

A ball mill is a machine (Fig. 17.6b) with a rotating hollow cylinder partly filled with steel or white cast iron balls. With brittle materials, the powder particles produced have angular shapes with ductile metals, they are flaky, and they are not particularly suitable for powder metallurgy applications. Dr.
