ABSTRACT:
A cylindrical housing having diametrically opposed inlet and discharge openings contains a bucket wheel coaxially rotatable therein. The inlet opening is provided with an insert having an inclined upper surface and an edge for prestripping the grain material. The insert is further provided with a stripping edge forming an angle with the cylindrical generatrix formed by the surface edge of the blades of the rotating bucket wheel which angle is at least equal to the angle of friction between the bulk material and the material out of which the gate is formed. In addition, a canopy displacing wall is arranged in the inlet opening at the level of the end of the stripping edge to displace the material moving through the feed inlet. The wall has a width of such a dimension that the cavity formed beneath it is equal to at least the volume of the granulate material stripped from the stripping edge.
