Abstract
Disclosed is a method of cooling hot agglomerates containing metallic iron resulting from prereduction of iron oxide, by moving ambient atmospheric air rapidly over the agglomerates so that little if any reoxidation of the metallic iron results. Also disclosed is apparatus comprising a gas permeable support movable in a generally horizontal generally circular path and having a feeding station at which hot particulate material is deposited on the support in a bed of substantially uniform thickness in which the particles are at rest relative to each other, discharge means at another station angularly spaced along the path of travel of said support for lifting the particulate material from the support, means for passing cooling gas through the bed of material on the support as the support travels from the feeding to the discharge station, and means for receiving the discharged cooled material. The discharge means includes a magnetic means movable sufficiently closely to the support to lift off cooled magnetic particulate material and drop it onto a conveyor.
