Title: BLASTING APPARATUS AND METHOD FOR BLASTING
Abstract:
Provided is a blasting apparatus having an enhanced capacity of absorbing abrasives without affecting blasting of a work surface using abrasives. The blasting apparatus comprises a jet nozzle (2) capable of directing abrasives (100) to a surface (200a) of a work (200), a cover (10) having a current guide surface (10a) parallel to the surface (200a) of the work (200) and an opening (10b) for the abrasives (100) ejected from the jet nozzle (2) to pass through, a nozzle case (9) enclosing the jet nozzle (2) and the cover (10), and a recycling case (11) covering the nozzle case (9) to form a recycling path (11c) surrounding the nozzle for the abrasives (100) to recirculate therethrough by suction. The abrasives (100) ejected from the jet nozzle (2), after hitting the surface (200a) of the work (200), are recycled via a gap (13) formed between the current guide surface (10a) of the cover (10) and the surface (200a) of the work (200) through the recycling path (11c).
