Abstract
L'invention se rapporte à un distributeur de poudre. Selon l'invention il comporte une trémie 1 fermée hermétiquement par un couvercle 2, relié à une source de gaz sous pression 4. Un arbre 5 est monté coaxialement à l'axe vertical de la trémie et s'étend jusqu'à proximité du passage de sortie 6 de cette trémie, tandis que sa partie supérieure est associée à un moteur d'entraînement 8. Cet arbre présente des bras 11 s'étendant radialement et à différents niveaux; son extrémité inférieure se prolonge par un excentrique 12 jusque dans le passage 6. Ce distributeur peut être associé à un conduit de transport pneumatique 13 aboutissant à une lance à injection. L'invention s'applique notamment à la désulfuration de la fonte ou au raffinage de l'acier.
