Abstract
The present invention relates to a process for the manufacture of fine propellant powders by granulation, and, by way of products, to the fine powders thus obtained. The process according to the invention consists in granulating the base materials, wetted with solvent, in a granulating tray 11, in subsequently subjecting the granules thus obtained to a first partial drying in a drier 14, and in completing the finishing of the said granules in a rounder 16, optionally in the presence of solvent. The process according to the invention can be carried out continuously or batchwise, with a very high degree of operational safety. The propellant powders thus obtained possess a good activity and are suitable for small-caliber and medium-caliber weapons.
