PURPOSE: A device for supplying a fixed quantity of abrasives to an air sand blast machine is provided to control the amount of abrasives and to preciously control the processing state of a product by controlling the frequency of a high frequency feeder. CONSTITUTION: A device for supplying a fixed quantity of abrasives to an air sand blast machine comprises a high frequency feeder(31), a vibration plate(34), and an abrasive delivery pipe(35). The high frequency feeder is installed in the bottom of an abrasive supply pipe(25) installed at a storage tank(23). The vibration plate is installed on the upper side of the high frequency feeder. The vibration plate has a plurality of conveying grooves. The abrasive delivery pipe is fixed to the end of each conveying groove of the vibration plate. If the abrasive of the storage tank falls upon the upper side of the vibration plate in the driving process of the high frequency feeder, the abrasive spreads in all directions and is transferred along the conveying groove to be discharged through the abrasive delivery pipe.
