The objective of the present work is the comparison of two common milling methods for the production of complex metallic alloy nanoparticles. γAl 12 Mg 17 nanoparticles were fabricated using both a planetary ball mill and a SPEX mill. The produced nanoparticles have been compared on the basis of the phase and microstructural characterisations by means of Xray diffraction (XRD) and field ...

1. Introduction. Planetary ball mills provide high energy density due to the superimposed effect of two centrifugal fields produced by the rotation of the supporting disc and the rotation of the vials around its own axis in the opposite direction [1].During operation, the grinding balls execute motion paths that result in frictional and impact effects.

Among highenergy ball mills, the planetary is a mechanically simple and versatile device for efficient grinding. It is usually made of two or more jars, rotating at an angular velocity ω around their axis (see Fig. 1), installed on a disk rotating at angular velocity Ω.Grinding occurs by impact among the milling media (balls and jars), driven by centrifugal and Coriolis forces, with ...
