The particle size of raw materials used for high energy ball milling should be in the range of 1–200 μm, smaller than that of the milling ball size. The ball mills mainly include shaker mills, attritor mills and planetary ball mills. For the preparation of alloy fuels, planetary ball mill is the most appropriate.

Attritor fits into the family of mills. For example, ball mills use large media, normally ½" or larger, and run at a low (10-50) rpm. The other mills, such as sand, bead and horizontal, use smaller media (from 1/64" to 1/8"), but run at a very high rpm (roughly 800-1200). High-speed dispersers with
