Abstract
An auger apparatus having an elongated housing for permitting granular, powdery or pelletized material to pass therethrough has an inlet is provided for introducing material to be conveyed into one end of the housing and an outlet for causing the material to drop therethrough to a desired destination, this outlet comprising a plurality of elongated openings disposed at least partially in a lower portion of the housing. An auger is disposed in the housing for moving the material therein in one direction through the housing. A motor is provided for rotating the auger about an axis in a direction to cause material disposed in the housing to move from the inlet to the outlet thereof. The lower portion of the housing is at least partially cylindrical in shape and the elongated openings have one end thereof closer to the inlet than to the outlet of the housing and these elongated openings also have one end thereof lower than the other end thereof. A larger opening thereof is disposed downstream from the outlet for receiving large undesirable lumps or chunks of material.
