Abstract

L'invention concerne un système pour refroidir des scories. Selon l'invention, il comprend un dispositif 2 pour convertir des scories fondues en granules de scories, un refroidisseur 3 du type à lit fluidisé avec un lit fluidisé 3a de particules solides où passe un gaz, un échangeur de chaleur 9 du type à lit mobile qui est en communication avec le fond du refroidisseur 3 et qui a un lit mobile de granules de scories où passe le gaz, et un tube de classification 8 reliant le refroidisseur 3 et l'échangeur de chaleur 9 pour classifier les granules de scories par rapport aux particules solides du lit fluidisé 3a. L'invention s'applique notamment aux scories obtenues du raffinage de divers metaux.
