<p>In blasting with an abrasive containing liquid to confer elasticity, the abrasive from which liquid evaporates in the course of continuance use is uniformly supplied with liquid. Liquid for swelling an elastic abrasive is sprayed in an air flow for transporting the abrasive in a blasting machine 1 including an abrasive-recovery duct 91 communicating between a bottom of a cabinet 2 and an abrasive-recovery tank 3, the abrasive-recovery tank 3, a compressed gas before being introduced into a blasting gun 8, and so forth. Since the abrasive being transported in the air flow is separated into individual particles, each abrasive can be uniformly supplied with liquid.</p> |
