Abstract

a. Procédé de réglage, de qualité de noir de fumée. b. Procédé caractérisé en ce qu'on mélange en continu avec de l'eau et on façonne en perles du noir de fumée au moyen d'une machine à fabriquer les perles par voie humide après quoi, pour obtenir une faible valeur pour le rapport entre l'indice DBP et l'indice DBP après compression, on règle à une vitesse élevée au moins un arbre de la machine à perles et/ou ajoute la quantité principale d'eau en un point de pulvérisation d'eau placé en amont, tandis que, pour obtenir une valeur élevée de ce rapport, on règle à une vitesse de rotation faible l'arbre de la machine à perles, et/ou introduit la quantité principale d'eau en un point de pulvérisation placé en aval, et on sèche finalement le noir de fumée en perles.
