ABSTRACT:
The cooling of the material is mainly achieved through the convective thermal exchange between the loose hot material and the cooling air flow blown in from the outside, and through the conductive thermal exchange between the same material (3) and the conveyor belt (2). In order to improve the efficiency of the cooling process appropriate slots (16) are made into the plates of the conveyor belt, through which the cooling air can be made to flow so as to reach the base of the travelling continuous bed consisting of hot material. Furthermore the abovementioned plates can be equipped with appropriate extensions which operate while immersed into the conveyed material, thus increasing the surface suitable for the conductive thermal exchange.
