APPARATUS FOR COOLING PARTICULATE MATERIAL

摘要

Apparatus for cooling calcined or sintered particulate material discharged from a rotary kiln or other pyroprocessing system. The apparatus includes an upright shell adapted to contain the material to be cooled, a mixing hopper arranged within the upper portion of the shell for mixing together particles of the material of different size and air distributing means arranged within the lower portion of the shell for releasing cooling air into the material. The apparatus is configured so that the cooling air moves counter to the direction of material flow.
