PURPOSE: A shot blasting apparatus with a dust emission blocking function is provided to increase working efficiency since after a shot blasting work has been completed, an additional task to remove dust from a steel sheet is not needed. CONSTITUTION: A shot blasting apparatus with a dust emission blocking function comprises an air spraying unit(110), an air tank(120), and a valve unit(130). The air spraying unit is arranged toward the inside of the outlet(12) of a shot blasting chamber(10). For dust discharged with a steel sheet(S) to be blocked, the air spraying unit sprays air. The air tank keeps air sprayed from the air spraying unit. The valve unit controls the spraying pressure of air and the flow of air sprayed from the air spraying unit. |
