Abstract

Le danger inhérent à la production de ce type de poudres réside dans le fait que des bulles d'éther se forment dans la poudre et en réduisent considérablement la qualité. La présente invention propose de refroidir la poudre de charge explosive avant qu'elle ne sorte du dispositif d'extrusion. Aussi la tête d'extrusion (4) est-elle munie d'un dispositif de refoidissement. Cette invention est conçue en particulier pour la fabrication de poudres de charge explosive monobasiques où un alcool ou un éther sert de solvant.
