Abstract
A process for producing prills containing an energetic material other than ammonium dinitramide (ADN) or ammonium nitrate (AN), is performed in a prilling column having at least one heated zone and at least one cooling zone. Solid particulate feedstock of the energetic material is introduced into said prilling column and allowed to fall through the heated zone and form melted particles as pre-prills. A countercurrent flow of inert fluid medium is sufficient for spheridization of the pre-prills into spherical pre-prills. The spherical pre-prills pass through the cooling zone in the prilling column, in which the spherical pre-prills harden into prills, while excessive condensation in the cooling zone is avoided. The prills are then collected.
