ABSTRACT:
A rotary air lock feeder has a cylindrical chamber closed at opposite ends by end walls and a rotor mounted for rotary movement along the cylindrical chamber axis. A hopper is provided for feeding material into an upper portion of the chamber. A port is formed in each of the end walls to one side of a vertical plane extending through the cylindrical chamber axis at a height above the angle of natural repose of the material. So constructed, material fed into the chamber may be driven by the rotor to the bottom of the chamber and then lifted by the rotor to a position between the end wall ports and become evenly entrained in an airstream flowing through the chamber between the ports.
