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.

The die of claim 2, further comprising: a plate coupled to the first face of the first body portion to seal the first body portion passage to prevent the leakage of resinous material from first body portion. 4. A die for coating a continuous strand with a resinous material comprising: a body including a first portion and a second portion; and a support, wherein said first and second body portions are separately coupled to said support, and said first body portion is pivotally coupled to said support and is moveable relative to said second body portion between an open position in which the strand is inserted into the die and a closed position in which said first and second body portions are fluidically coupled, wherein said die includes first and second conduits coupling said first and second body portions to said support, respectively, and said first and second conduits are adapted to supply the resinous material from said support to said first and second body portions simultaneously. 5. The die of claim 4, wherein said first body portion includes a flow channel that is adapted to direct the resinous material to coat the strand. 6. The die of claim 5, wherein said die further comprises: a plate coupled to said first body portion to seal said flow channel. 7. An apparatus for coating a continuous strand with a coating composition, the apparatus comprising a support body, a die, a plate, an actuator, and a plurality of conduits, wherein: the support body comprises a port for receiving the coating composition and directing the coating composition to the conduits; the die comprises a first body portion, the first body portion comprising a first longitudinal channel formed on and extending completely across a first face, a first passage formed through the first body portion to establish a fluid connection between the first channel and a first opening on a second face and a recess provided on the first face for receiving the plate, the first body portion maintained in a substantially fixed position relative to the support body; a second body portion moveable relative to the first body portion, the second body portion comprising a second longitudinal channel formed on and extending completely across a third face and a second passage formed through the second body portion to establish a fluid connection between the second channel and a second opening on a fourth face; the plurality of conduits comprise a first conduit arranged and configured to extend between the support body and the first body portion and provide both a primary mechanical support for the first body portion, and a fluidic connection whereby a portion of the coating composition exiting the support body is directed through the first conduit, through the first opening and into the first passage and a second conduit arranged and configured to extend between the support body and the second body portion and provide both a primary mechanical support for the second body portion and a fluidic connection between the support body and the second body portion whereby a portion of the coating composition exiting the support body is directed through the second conduit, through the second opening and into the second passage; and the actuator being selectively operable to move the second body portion and the second conduit between a first portion and a second position, wherein in the first position the third face is in contact with the first face and the plate, the first and second longitudinal channels cooperating to form a duct through which the continuous strand may pass, the duct having an inlet for receiving the continuous strand and an outlet for removing the continuous strand coated with a coating composition and the contac
