Attritor mills are known for the production of large quantities of alloys (0.5—100 kg). Planetary mills offer a variety of options for milling volume and input energy can be varied. Some of the planetary ball mills with smaller size are capable of imparting high input energy with a speed of as much as 1000 rpm (For example Fritsch planetary P-9).

velocity), which enables us to see how the Attritor fits into the family of mills. For example, ball mills use large media, normally 1/2"or larger, and run at a low (10-50) rpm. The other mills, such as sand, bead, and horizontal, use smaller media from 0.3mm to 2mm, but run at a very high rpm (roughly 800-1200).
