Abstract (en)

[origin: US5266242A] PCT No. PCT/EP90/00616 Sec. 371 Date Jan. 7, 1991 Sec. 102(e) Date Jan. 7, 1991 PCT Filed Apr. 17, 1990 PCT Pub. No. WO90/13528 PCT Pub. Date Nov. 15, 1990.The invention relates to a method of and an apparatus for producing tribasic propellant charge powders. An operationally safe and continuous course of the production process is obtained according to the invention by first preparing a fully gelatinized dibasic intermediate product of nitrocellulose and a blasting or explosive oil, without solvent, in a shearing mill (1). The intermediate product is granulated and supplied to an extruder (4) into which the third crystalline energy carrier and solvents are introduced. There the pulverous mixture is homogenized and extruded to form powder strands which are moist with solvent.
