PURPOSE:To improve feeding ability for a powdery and granular particle, by connecting injectors of peculiar construction for feeding air to the with a feed pipe in its suction port and every important part. CONSTITUTION:An air generating machine 13, if it is actuated, introduces its pressurized air X in the connection direction of an internal wall with a downflow air passage D in the main unit of a casing 1 from a connection port 2A of a connection pipe 2 through supply air pipes 15. And the air, which strikes an arc-shaped bottom wall part 4 changing the direction and being allowed to flow into an upflow air passage u, is jetted in a relatively large turning pitch toward an outlet side from the periphery of a throat part 3A of a tapered pipe 3 while the air is guided turning by a turn guide vane 9. A negative pressure, which is formed by turning force of the air, attracts a powdery and granular particle Y, placed in an introduction side, to be sucked into the main unit of the casing 1, and the is fed toward a feed pipe 11 in the outlet side from feed passage T. While also in a part of the feed pipe 11 providing an injector I to be arranged halfway the pipe, the particle Y, to which turn feeding force is suitably supplimented, is discharged to the outside from a discharge chute 12.
