Abstract

Bulk material cooling comprises includes a conveyor having a support surface for transporting bulk material from the conveyor inlet to its outlet. A first material supply chute is provided at the inlet for depositing a quantity of relatively cool material on the conveyor. A baffle is located downstream of the supply chute for leveling the material on the conveyor and forming a uniform thickness layer of such material. A second material supply chute is arranged downstream of the baffle for depositing a layer of relatively hot material atop the first layer. The first layer of material protects the conveyor from the heat of the second layer. Cooling air is passed upwardly through the first and second layer to cool the material.
