ABSTRACT:
A hopper device for delivering granular or powdery material to a conveyor system of a type having a circuitous tube and a continuous flexible member having disc members rigidly attached thereto has a material level monitor and control apparatus attached thereto. The continuous flexible member passes through the hopper and a material flow varying mechanism is disposed within the hopper for causing material to be delivered from the hopper into the conveyor system when such mechanism is in operation. A housing having a chamber therein is attached to the outlet side of the hopper and has a float assembly disposed in the chamber for sensing the amount of material being fed into the conveyor system. A mechanism is furthermore provided for linking the operation of the mechanism for varying the amount of material delivered to the conveyor system in response to the movement of the sensing mechanism and float whereby when the conveyor system is running continuously, the conveyor tube will always be running full of material, but will never be overloaded.
