ABSTRACT:
A storage bin with multiple discharge openings is provided for particulate material. A bottom wall of the bin has a plurality of discharge openings, preferably an even number, with half of them spaced closer to the center line of the bin than the other half. More specifically, the outer half are positioned adjacent the side wall of the bin and the inner half are spaced from the center line by three-fourths of the distance from the center line to the side wall. Each half is also equally peripherally spaced around the bin. The bottom wall preferably is of inverted conical shape and can have a cone centrally positioned thereon, with the periphery of the cone located inwardly from the inner discharge openings. Portions of the cone periphery can be spaced from the bottom wall to enable particulate material to flow down below the cone to a central discharge duct having a valve which is opened from time-to-time.
