In the processing of ultra-fine powder, dispersing and disaggregating is also an important link, and there are many equipment used to disperse ultra-fine powder, and jet mill is one of them. Jet mill is often used for dry dispersion of agglomerated powder. Its advantages are high particle size reduction rate, no damage to the original morphology of particles, and strict control of large particles.

Wet Milling instead of dry milling is often advantageous because liquids tend to break up agglomerates as well as reducing re-welding of powder particles. As milling media, hydrocarbons (hexane, heptane), ethanol and other organic liquids, which help to avoid oxidation of the milled product, are often used.
