BLAST PROCESSING DEVICE AND BLAST PROCESSING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a blast processing device enabling more efficient blast processing.SOLUTION: A blast processing device is provided with an injection section and a circulation system. The injection section injects a media having a weight difference of a threshold or more and exceeding the threshold between the media and powder dust of a resin falling off from a composite material to a workpiece structured of the composite material. The circulation system collects the media after injection, and supplies the media to the injection section. The circulation system is provided with an impurity separation section which removes at least one of impurities included in the collected media and media having the reduced particle size.SELECTED DRAWING: Figure 4
