Improved Mixing, Granulation and Drying of Highly Energetic Pyromixtures,
PINE BLUFF ARSENAL AR
Pagination or Media Count:
A safer and more efficient method of mixing, granulating and drying MIGRAD highly energetic UN 1.1 pyrotechnic composition will be reported. The process uses a MIGRAD mixergranulator that was tailored to mix, granulate and dry a pyrotechnic material 20-40 lbs. within a single mixing chamber. Features of the process include remote loading and unloading, reduced solvent, shortened mixing cycle 40 minutes, infinitely variable speed control of mixing and granulating impellers, built-in state-of-the-art fire detectionsuppression UV-50MS, IF-10MS, explosion venting, heated-chamber, vacuum drying, remoteprogrammable controls, and remote mixer cleanup using energy of the mixer. The mixing process will be evaluated for preparation of some 24 pyrotechnic compositions for five ArsenalsAmmo Loading Plants. Hazards Classification Safety Data Sheets were prepared for the 24 pyrotechnic compositions and will be reported along with resultant physical properties of the completed compositions.
