Abstract

La présente invention se rapporte aux triturateurs et aux malaxeurs en continu à arbre moteur horizontal. L'appareillage comprend préférentiellement, une goulotte semi-circulaire surmontée par des parois verticales parallélépipédiques, et un agitateur constitué par un arbre concentrique à la goulotte et porteur de pales rigides perpendiculaires à cet arbre, au moins une desdites pales sur quatre étant prolongée par une languette frottant contre la goulotte, les matériaux constitutifs des divers éléments susceptibles d'entrer en contact avec les grains de poudre propulsive étant conducteurs de l'électricité. Appareillage permettant la mise en oeuvre de traitements de surface en continu des poudres propulsives en grains.
