PROBLEM TO BE SOLVED: To obtain a shot processing device that can optimize a particle size of a shot material while downsizing the device.SOLUTION: A pressurizing tank 42 is disposed below a shot position 24X at which a workpiece 12 is processed, and a shot material that has been shot is received in the pressurizing tank 42 through a hopper 44. In the pressurizing tank 42, an outlet side can communicate with a shot processing machine. One end of a discharge-side pneumatic conveying pipe 54 provided with a suction function is connected to the hopper 44. The other end of a discharge-side pneumatic conveying pipe 54 is connected to a vibration sieve 68. The vibration sieve 68 is connected to one end of a supply-side pneumatic conveying pipe 76 provided with a suction function. The other end of the supply-side pneumatic conveying pipe 76 is connected to a case 80 communicating with a shot processing chamber 16. |
