ABSTRACT:
Finely divided pellets or granules are formed from a molten explosive comition by a combination of spray chilling and prilling techniques, which comprises atomizing the molten explosive composition in a high velocity stream of an inert gas such as air and allowing the atomized droplets to fall through a tower countercurrent to a stream of an inert gas to cool the droplets to form solid pellets. The process is advantageously employed for producing meltable explosive materials, e.g., Composition B, in the form of free flowing spherical pellets of high density and uniform composition.
