The invention aims at providing a bulk material cooler particularly for hot cement clinker, wherein the conveyance performance and the efficiency of the cooler are enhanced and problems due to wear are reduced. According to the invention, the cooling grates of several adjacent, elongated bottom elements (10 to 12) extending in longitudinal direction of the cooler are put together, said bottom elements being movably controlled independently of one another between a work clearance stroke position (13) in the direction of conveyance of the material to be cooled and a return stroke position (14) in such a way that the material to be cooled (15) is gradually conveyed through the cooler according to the walking floor transport system, wherein the bottom elements (10 to 12) are configured as hollow bodies and enable the cold air (16) to go through yet prevent grate sifting of the material to be cooled.
L'invention concerne un refroidisseur de matière en vrac, destiné notamment à du clinker chaud. L'objectif de l'invention est d'accroître la capacité de transport et le rendement de ce refroidisseur et de réduire les problèmes d'usure. A cet effet, la grille de refroidissement est constituée d'une pluralité d'éléments de fond (10 à 12) allongés, juxtaposés, s'étendant dans le sens longitudinal du refroidisseur. Ces éléments peuvent effectuer un mouvement de va-et-vient de manière commandée, indépendamment les uns des autres, entre une position "aller" (13) et une position "retour" (14), dans le sens de transport de la matière à refroidir, de sorte que cette dernière (15) est transportée progressivement à travers le refroidisseur selon le principe du fond mouvant alternatif (walking floor). Les éléments de fond (10 à 15) se présentent sous la forme de corps creux permettant le passage de l'air de refroidissement mais empêchant la matière à refroidir (16) de passer à travers.
