To provide an air and water conveyor/cooler for hot loose materials such as heavy ashes produced by boilers or ashes and slag produced in various industrial processes of burning and baking.

The air and water conveyor/cooler for hot loose materials mainly comprises a regulated metal container 1 connected to a boiler 2 or to an incinerator, a material 3 that leaves a combustion chamber falls from the boiler or the incinerator due to the gravitational effect. Inside of the container 1, a metal conveyor belt 4 is placed, the hot loose material 3 to be cooled is placed on the same. The cooling of the material 3 occurs through the feeding of an air flow picked up from the outside environment integrated with atomized water sprinkled onto the hot loose material 3 through a system of injecting nozzles 5 installed inside of the metal container 1.
