This blasting device is provided with: a blasting nozzle that mixes and ejects compressed air and an ejection material aspirated within a nozzle holder; a casing that houses the blasting nozzle; a classification mechanism connected to the casing; an aspiration mechanism connected to the classification mechanism; and a storage hopper that stores reusable ejection material classified by the classification mechanism. Also, the storage hopper is positioned below the blasting nozzle, and so an ejection material conveyance mechanism is further provided for conveying to the blasting nozzle the ejection material stored at the storage hopper, and as a result it is possible to convey the ejection material to the blasting nozzle in a stable manner. |
