Screw Conveyor Discharge Spouts

Discharge spouts are typically located at one end of a screw conveyor on the bottom of the trough. Bulk materials exit a screw conveyor through the discharge spout. Multiple discharge spouts with slide gates can be used to distribute bulk materials to various downstream processes. Slide gates should not be used on the final discharge of a screw conveyor because if the slide gate is closed, bulk materials will be compressed against the trough end and cause damage to the screw conveyor.

Nomenclature

Standard

Standard discharge spouts are continuously welded to the bottom of a U-trough or tubular housing and can be located anywhere along the length of a screw conveyor. A minimum distance is required for the final discharge spout to allow for welding of the plate end flange and discharge spout.

Flush End

Flush end discharge spouts are continuously welded to the end of a U-trough or tubular housing in order to maximize the length of the trough. A special flush end trough end is required with a flush end discharge. The discharge is considered ”flush” with the trough end.

Hand Slide

A hand slide gate is the simplest form of slide gate and utilizes a slide plate, spacer and retainer flange bolted to a standard discharge spout.

Open End

Open end discharge spouts utilize a hanger, hanger bearing and end shaft to allow bulk materials to discharge out the end of a screw conveyor. Open end discharges allow for maximum conveying distance over the length of the trough.
