Vertical Screw Conveyors
As the name suggests, these Vertical Screw Conveyors, are in vertical position saving a lot of space. They convey, or say transfers the granules and powered material from lower to a higher level. They are very economical and serve as lifts. The Vertical Screw discharges the bulk material withdrawn from a silo, hopper, conveying or feeding device into a weigh hopper, into one or more bins or silos, or into another conveyor or conveying system.
Vertical Screw Lift Systems excel through high volumetric efficiency and excellent mechanical features.
Vertical screw conveyors design
The Vertical Screw Conveyors or Lift System consists of a Horizontal Screw Feeder and a Vertical Screw Conveyor. The material is fed by a Horizontal Screw Feeder from a silo or hopper or conveying is fed by an upstream feeding device, includes 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. At each end of the Horizontal Screw Feeder, a flange is welded. 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 which are required on overall length along with it a drive unit is also used as per the suitability of the application.
