This high energy ball mill agitates the charge of powder and balls in three mutually perpendicular directions at approximately 1200 rpm. Ball velocities in such shaker mills are high, o m/s. A given reaction, such as amorphization, can typically take place an orderofmagnitude faster in the Spex mill than in the usual vibratory or attritor mill.

1. Introduction. High energy ball milling (HEBM) is known as an economic, simple and yet powerful method for the production of nanostructured and amorphous materials [1].The prolonged milling of powder mixtures, results in the formation of supersaturated solid solution, nonequilibrium intermetallic compounds as well as the formation of silicides, nitrides, stable or unstable carbides [2].
