Abstract RU 2105743 C1

FIELD: processing of pyroxilin gunpowder. SUBSTANCE: pyroxilin gunpowder is preliminary ground to particles 0.8-2.2 mm, the process takes place in aqueous medium. Then grinding to particles 0.2-0.7 mm in size is carried out. Then gunpowder crush is squeezed against water and dried till moisture content is 2-5 %. Then fractionation followed by final drying to moisture content 0.8-1.0 % takes place. Then mixing is carried out, thus physical and chemical features are adjusted. EFFECT: improved efficiency. 1 tbl
