Earlier investigators have utilized attritor mills and wet milling (slurry of metallic powder with liquid nitrogen) to prepare metallic nanoparticles. Zheng et al. [12] have reported that it is possible to reduce the particle size of Mg alloy (AZ80) from 55 μm to 10–30 μm after 8-h cryomilling while average grain size is reported to be 40 nm.

velocity), which enables us to see how the Attritor fits into the family of mills. For example, ball mills use large media, normally 1/2"or larger, and run at a low (10-50) rpm. The other mills, such as sand, bead, and horizontal, use smaller media from 0.3mm to 2mm, but run at a very high rpm (roughly 800-1200).
