ABSTRACT:
A substantially continuous flow is attained in the unloading of a bulk particulate from a storage hopper by monitoring the pressure differential between the hopper and a point in the discharge line downstream of the hopper outlet. The pressure differential is sensed by a pressure switch in the discharge line which activates a vibrator on the hopper near the outlet when the differential is at a first predetermined value and deactivates the vibrator when the differential is at a second predetermined value, thereby maintaining the flow and reducing mechanical damage to the hopper.
