The present invention relates to a reducer type air-lock screw feeder. The screw feeder including an air-lock function is applied to block a raw material and compressed air reversely flowing in an ejector during transportation of a pulverulent body in a pneumatic method instead of using an air-lock rotary feeder. The reducer type air-lock screw feeder has an excellent property of blocking the compressed air in comparison with the rotary feeder and minimizes damage to a product due to the raw material and the compressed air to obtain stable life of the product and enable stable process operation. Moreover, the reducer type air-lock screw feeder can maintain a service level or a quality of a final product by enabling stable supply of the raw material, thereby maintaining a management level of a production quality. |
