ABSTRACT:
A constant discharge device for a pneumatic conveyor for powdery or granular materials includes a discharge regulator valve disposed in a pressure tank that stores the powdery or granular material and movable toward or away from a discharge nozzle which has an open end through which the material is discharged out of the pressure tank into a conveyor pipe. The discharge regulator valve has an air outlet for ejecting a stream of air toward the discharge nozzle. The amount of the material as discharged into the conveyor pipe can be controlled by adjusting the position of the discharge regulator valve with respect to the discharge nozzle, and also by adjusting the rate of flow of air through the outlet of the discharge regulator valve.
