vertical screw conveyor rpm calculation

  • ENGINEERING GUIDE Screw Conveyors

    Inclined screw conveyors typically operate from slightly above the horizontal position to 45-degrees from the horizontal position. Above 45-degrees an inclined screw conveyor is considered a vertical screw conveyor and must be designed in accordance with the KWS Engineering Guide for Vertical Screw Conveyors.

    To calculate the screw feeder speed, you simply divide the desired capacity (ft 3 /hr) by the standard figure in Table 1 (ft 3 /hr/RPM). Thus, the final unit of screw feeder speed is RPM, which stands for Revolutions Per Minute. Compared to screw conveyor speed, screw feeder speed should be slower in order to achieve the optimal efficiency.
