Abstract

Lors de la production de granulés de matières fondues, une partie du produit est présente sous forme de vapeurs qu'il faut éliminer de l'air d'évacuation. A cet effet, il est prévu d'utiliser les produits en morceaux résultant de la production, notamment des pastilles, directement pour former un lit fixe de matières en vrac (8), introduit dans le flux d'air d'évacuation et servant à cristalliser le soufre contenu dans la proportion de produit présente sous forme de vapeurs. L'invention s'applique à la production de pastilles de soufre.
