201223This high energy ball mill agitates the charge of powder and balls in three mutually perpendicular directions at approximately 1200 rpm. It is highly energetic compared to the attrition and vibratory mills. A given reaction can typically take place an order-of-magnitude faster in the SPEX mill than in the typical attritor or vibratory mill.
