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 order-of-magnitude faster in the Spex mill than in the usual vibratory or attritor mill.
