Abstract

La présente invention concerne le refroidissement de produits solides pulvérulents. Elle décrit un procédé de refroidissement d'un tel solide, caractérisé en ce qu'il consiste à réaliser la fluidisation du solide pulvérulent ; à compartimenter le lit fluidisé ainsi réalisé de façon à obtenir des lits fluidisés communicants; à injecter au sein du solide pulvérulent en suspension, dans au moins un et dans au plus la totalité moins un compartiment, un fluide refroidisseur; à recueillir le solide pulvérulent à la sortie du ou des compartiments où a été réalisée l'injection. Elle décrit également un dispositif permettant de mettre en oeuvre le procédé. L'invention est applicable au traitement des minerais.
