In comparison with conventional ball mills, Attritors use fewer resources, including: In addition, Attritors offer the advantage of being able to take samples at any time and making formulation adjustments during high energy ball milling. Alternatively, ball mills are closed systems and do not offer these advantages.

The cost of edge drive is low, but the pinion needs to be replaced every 25 years. Edge drive is mainly used in coal mills and mills with small power. The girth gear(big ring gear) and pinion are the key of the edge transmission device. Their reliable operation is directly related to the stable production of the mill.

For instance, the conical mills at Inspiration were 16 in. longer between the bearings than the Marcys, with less than half the capacity. The Marathon, or rodmill, has not been adopted as quickly as one would expect. Undoubtedly it requires more care than a ballmill, and its mechanical troubles offset its power efficiency in some degree.
