Process and device for the production of propellant granulate

: Mueller, D.; Bauer, H.

Abstract
Several small-diameter propellant strands are continuously extruded for the production of propellant granular material, deposited separately on a plate downstream of the extruder and conveyed on said plate over a setting section, then, on a downward section and under the effect of its own weight, said strands are fed to a cutting plate having a number of guide holes corresponding to the number of strands and, on emerging from the guide holes, are cut to the desired length by means of a rotating cutting knife located behind the cutting plate.
