PROBLEM TO BE SOLVED: To provide a system for reusing the blast drain of an ice blasting apparatus, which system can efficiently reuse the blast drain from a blasting section. SOLUTION: The blast drain discharged from the blasting section 1 for ice-blasting the surface of a workpiece W by blasting ice powder together with water is recovered to a blast drain tank 9. The blast drain recovered in the blast drain tank 9 is successively supplied according to the decrease of the volume of the cleaning drain in a cleaning drain tank 22 in a cleaning station and the decrease of the volume of the coolant in a centralized coolant tank 32 in a machining station. Therefore, a newly required volume of a cooling fluid can be greatly reduced in the cleaning station, and further a newly required volume of a diluted fluid can be greatly reduced in the machining station, and in addition, the blast drain can be efficiently reused. As a result, the total water consumption in the ice blasting process, the cleaning process, and the machining process can be greatly reduced. COPYRIGHT: (C)2006,JPO&NCIPI
