  • Method and apparatus for maintaining uniform mass flow of granular material out of a container
    Patent number: 5906293
    Abstract: A method and apparatus for maintaining a substantially uniform mass flow of granular material out of a container. The apparatus includes a converging transition portion defining an input opening which converges to an output opening. The output opening has a transverse opening dimension (x). An elongated chimney portion is coupled to the converging transition portion at the output opening. The elongated chimney portion has a height dimension (y) The ratio of the transverse opening dimension (x) relative to the height dimension (y) is determined by an angle of repose of the granular material to maintain a substantially uniform mass flow of granular material.
