Abstract

L'invention a pour objet un procédé et une installation de refroidissement de minerai dans une installation d'agglomération comprenant une zone de cuisson et une zone de refroidissement et un moyen de concassage de l'aggloméré, celui-ci contenant une certaine partie de gros morceaux à la sortie de l'installation. Selon l'invention, on ne refroidit pas complètement les gros morceaux dans la zone de refroidissement et à la sortie de ladite zone on sépare les gros morceaux du reste de l'aggloméré suffisamment refroidi, puis on fait subir refroidissement complémentaire auxdits gros morceaux et on les ajoute ensuite au reste de l'aggloméré. L'invention s'applique spécialement aux installations de préparation de minerai de fer aggloméré pour l'alimentation de hauts fourneaux.The object of the invention is a method and an installation for cooling ore in an agglomeration installation comprising a cooking zone and a cooling zone and a means for crushing the agglomerate, the latter containing a certain part of large pieces at the exit of the installation. According to the invention, the large pieces are not completely cooled in the cooling zone and at the outlet of said zone the large pieces are separated from the rest of the sufficiently cooled agglomerate, then the said large pieces are subjected to additional cooling and the said large pieces are then subjected to additional cooling. then add them to the rest of the chipboard. The invention applies especially to plants for preparing agglomerated iron ore for feeding blast furnaces.
