To provide an abrasive blasting method which carries out abrasive blasting by ejecting an abrasive to a workpiece, and efficiently removes only impurity from mixed particles including the abrasive after the abrasive blasting and the impurity produced by the abrasive blasting, and also to provide blasting equipment.
The abrasive blasting method comprises: an abrasive blasting step 1 of carrying out the abrasive blasting by ejecting the abrasive to the workpiece; a recovering step 2 of recovering the abrasive ejected to the workpiece and the impurity produced by the abrasive blasting, a dust removing step 3 of removing fine dust from the mixed particles recovered in the recovering step; a quantitative feeding step 4 of quantitatively feeding the mixed particles from which the fine dust is removed in the dust removing step; a screening step 6 of screening the mixed particles supplied from the quantitative feeding step, depending on dry specific gravity; and a reusing step of reusing the screened ejecting material screened in the screening step as the abrasive to be ejected to the workpiece.
