Planetary ball mill is a most frequently used system for mechanical alloying since only a very small amount of powder is required. Therefore, the system is particularly suitable for research purpose in the laboratory. The ball mill system consists of one turn disc (turn table) and two or four bowls.
Ball mills are a fundamental part of the manufacturing industry in the USA as well as around the world. Ball mills crush material into various sizes and extract resources from mined materials. Pebble mills are a type of ball mill and are also used to reduce the size of hard materials, down to 1 micron or less.
The synthesis of electrolytic grade iron (Fe) nanopowder was done by using planetary ball milling. It was found that the average crystallite size of the iron powder after 20 h milling was 32 nm. The high performance polymeric composites based on poly (aryletherketone) (PAEK) as a matrix and Fe as filler were prepared by planetary ball milling followed by hot pressing.
