The VE Vertical Screw Lift System consists of a Horizontal Screw Feeder and a Vertical Screw Conveyor.
The Horizontal Screw Feeder feeding material from a silo or hopper or conveying it fed by an upstream feeding device, consists of a U-shaped or tubular carbon steel trough with appropriate surface finishing. The outlet zone of the horizontal screw feeder consists of a short tubular section tangentially flanged at a right angle on the bottom section of the Vertical Screw Conveyor. A flange is welded at each end of the Horizontal Screw Feeder. The trough or tube contains a rotating screw with coupling bushes at each end connected with the shafts of the two end bearing assemblies. The Horizontal Screw Feeder is equipped with one or more intermediate hanger bearings should its overall length require them. Furthermore, the Horizontal Screw Feeder is equipped with a drive unit suitable for the application.
The Vertical Screw Conveyor consists of a tubular housing complete with the above-mentioned tangential inlet in the bottom section which connects with the outlet of the Horizontal Screw Feeder, an inclined outlet spout in the top section, end flanges welded on each conveyor tube section, a rotating screw in one or more sections with shaft coupling bush at each end, a base bearing assembly complete with slide bush, and a number of intermediate hanger bearings should the overall height of the conveyor require them. The top-mounted drive unit with integrated end bearing assembly (from which the screw is suspended) and self-adjusting shaft seal is suitable for the application.
The VE Vertical Screw Lift System is available in a medium heavy-duty version only.
