Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a steel ball recovery device and a steel ball recovery method for a shot cleaning device preventing temperature rising of steel balls due to contact of the steel balls with high temperature dust for a long time. SOLUTION: In a steel ball separating device of the shot cleaning device, the steel balls are spread on a heat transfer tube and the dust adhered to the boiler heat transfer tube is removed, the dust is recovered along with the spread steel balls, and the steel balls and the dust are cooled and separated. A separating device of a trommel structure is connected to a boiler lower part via a supply chute 3, and a powdery dust chute 2a recovering powdery dust 15 and a steel ball recovery chute 2b recovering the steel balls 14 are disposed in a lower part of the separating device.
