High Energy Milling Powder Metallurgy Beyond Discovery
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.
