### Mechanical Milling a Top Down Approach for the Synthesis

operated just short of the critical rotational speed at which centrifugal force "pins" the balls to the mill chamber wall. For large scale production of commercial alloys attrition mills have been largely replaced by the large tumbler ball mills. Another type of mill that has been used for pilotsizeproduction is the vibratory tube mill.
