Abstract
A bulk material conveying system includes a closed chamber having an inlet and an outlet and a conveyor communicating with the chamber outlet for receiving bulk material from the chamber. A pressurized gas is supplied to the upper portion of the chamber and to the conveyor to provide a pressure differential in the chamber which causes the bulk material in the chamber to flow through the outlet and conveyed through the conveyor. A pressure regulator is provided for automatically maintaining the pressure in the upper portion of the chamber at a predetermined value not to exceed a pressure sufficient to maintain the pressure differential during normal material flow rate conditions.
