In a feeder for granular material the material passes in a controlled manner from a mass thereof downwardly through a central feed aperture in a horizontal feed plate which is driven in a horizontal orbital path above a bottom wall having a discharge aperture therein. An annular plate overlies the periphery of the feed plate for the purpose of reducing the tendency of the feed plate to become jammed by the granular material. To further reduce this tendency the feed plate has studs projecting from its lower surface into sliding contact with the bottom wall, and inner and outer rings are provided between the inner and outer edges, respectively, of the feed plate and the bottom wall so as to orbit with the feed plate. |
