PROBLEM TO BE SOLVED: To provide a centrifugal projection type shot blast device to effectively utilize heat generated during processing of shot blast, increasing a life of the parts of the centrifugal projection type shot blast device which are early deteriorated as a result of the parts being heated thereby, and be utilized as the heat source of the heating apparatus of a fore and aft processing device situated fore and after the shot blast device. SOLUTION: In a centrifugal projection type shot blast device 3 to apply descaling of steel products, shot peening of steel parts or processing before painting by projecting a shot made of a metal through a centrifugal projector 3, a heat exchange mechanism by a powder or fluid-form heat medium R is constituted at least one of the side wall of a projection chamber 3A, the side wall of an exhaust duct 7, and a shot tank 3E to refuse shots S by recovering them.
