  • Wet grinding of crystalline energetic materials
    Patent number: 5197677
    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.
    Type: Grant
    Filed: April 26, 1991
    Date of Patent: March 30, 1993
    Assignee: Thiokol Corporation
    Inventors: Lee C. Estabrook, Carlos Somoza
  • Process for reducing acidity of unrecrystallized explosives by wet grinding
    Patent number: 5020731
    Abstract: Occluded acidity in particulate explosives is removed by slurrying the particles in an inert liquid and subjecting the slurry to wet-grinding. The inert liquid may include an alkaline salt at or near saturation. Separation of the ground explosive particles from the liquid phase results in a ground explosive material with much reduced acidity.
