Abstract: A process for the preparation of ''''Gudol powder'''' from a mixture of nitrocellulose, diglycol dinitrate, nitroguanidine, and additives, wherein an aqueous raw mixture of nitrocellulose and diglycol dinitrate is premixed with the other components, the said final mixture then dehydrated in part, plasticized, and finally pressed into the final shape of the powder product. The improvement in the process comprises reducing the water content of the premixed components in a first drying stage, then homogenizing and preplasticizing the premixed components in a continuously operating masticator, thereafter further reducing the water content of the composition in a second drying stage, thereupon plasticizing and converting the composition into granular form in a continuously operating extruder, adjusting the moisture control of the granulated material to a required pressing or extruding moisture, and finally extruding the granulated material to the final shape of the powder product in a continuously operating extruder.
