Ball milling is a size reduction technique that uses media in a rotating cylindrical chamber to mill materials to a fine powder. As the chamber rotates, the media is lifted up on the rising side and then cascades down from near the top of the chamber. With this motion, the particles in between the media and chamber walls are reduced in size by ...

The high energy of these mills is derived from the very high rotation speeds that are achievable. For example, Salimon et al. used their planetary ball mill at a rotation speed of 1235 rpm corresponding to the mill energy intensity of 50 W/g. It has been reported that some of these mills can be used at rotation speeds greater than 2000 rpm.

In the present study, WO 3 and CuO powders were ball-milled with high energy at 400 rpm for 1-50h in Ar atmosphere. They were examined using XRD, SEM and TEM. After the sieved WO 3-CuO powders were reduced in dry hydrogen, the reduced W-Cu powders were liquid-phase sintered at 1200 and 1300°C for 1h in dry hydrogen. After ball-milling of 1h ...
