摘要： An constant abrasive feeder of abrasive grains M is formed of a reservoir supply section 20 having a reservoir tank 21 and a buffer tank 31, a stirring hopper 40 for stirring abrasive grains S, and a vibration feeder 60 for supplying the abrasive grains S to an abrasive jet nozzle 5. The abrasive grains S recovered in a cyclone 1 is reserved in the reservoir tank 21 and the buffer tank 31 by a constant quantity, the abrasive grains S is sent from the buffer tank 31 and reserved in a reservoir 43, which is stirred by stirring bars 50, 51 and sent to a supply guide 45. Then, the abrasive grains S is sequentially supplied to a feeder body 61 of the vibration feeder 60 from an opening formed in the supply guide 45.
