Abstract

The invention relates to the cooling of hot bulk material, particularly cement clinker, ore material or the like, in a grate cooler, in which the bulk material is transported on the cooler grate surface toward an outlet and exposed to cooling gas from below. At least a part of the relatively cooler lower portion of the material layer is discharged through suitable chutes upstream of the cooler outlet while in transport to increase the cooling efficiency of the process.
