Screw Feeder Speed. 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 …
