Abstract
The particle size of a particulate energetic material such as HMX or RDX is reduced by introducing the energetic material as a water-containing slurry at less than 40 percent solids into a high velocity fluid stream in a fluid energy mill and controlling the fluid temperature, fluid velocity, and energetic material feed rate to achieve a particle size of about 10 microns or less.
