A device for spraying bulk or piecemeal products includes a casing with a rotary spraying organ and a lateral ejection opening prolonged by a spout. The rotary organ includes radial vanes designed to form a material jet directed along the axis of the spout, with generation of a carrier air stream. The ejection opening is provided with a bounding rim disposed on that side of the opening which is last to be reached by the outer peripheral ends of the vanes in the course of their rotation during operational functioning of the device. The spraying device also includes an active and mobile organ, designed for directing the products that come into contact with it through the opening, into the spout and substantially into the jet of ejected material. The active and mobile organ is disposed in the region of the rim. |
