BLAST PROCESSING APPARATUS AND BLAST PROCESSING METHOD

摘要

The present invention is to provide a blast processing apparatus for efficiently performing blast processing. The blast processing apparatus according to an embodiment of the present invention comprises an injection part and a circulation system. The injection part injects media, which have a weight difference greater than or equal to a threshold with respect to the dust of resin falling from a composite, to a work made of the composite. The circulation system collects the media after the injection and supplies the collected media to the injection part. An impurity separating part, which removes at least one among impurities contained in the collected media and media having a reduced particle size, is installed in the circulation system.
