ABSTRACT:
A high-pressure conveyor discharges a powdery or granular material from a pressurization tank through a discharge unit into a conveyor pipe. The discharge unit includes a guide cylinder or trough mounted on the tank, a screw feeder extending through the guide cylinder and having an end extending into the tank in overhanging relation to an aerator in the tank and the other end coupled to a variable-speed drive unit such as a motor. The material as it is fluidized on the aerator under a high pressure is supplied into the discharge cylinder, from which the material is fed by the screw feeder out of a discharge port in the guide cylinder into the conveyor pipe. A plurality of discharge units may be connected to the tank at angularly spaced intervals for uniform or adjusted distribution of the material to a plurality of locations.
