DetailsThe speed of the screw feeder can be determined by dividing the maximum screw feeder capacity in cu ft/hr by the capacity of the control pitch in cu ft/hr per RPM. Most screw feeder speeds are lower than standard screw conveyor speeds. For example, in heavy industrial applications, screw feeders typically operate at speeds less than 20 …
DetailsNote that screw speed and rate output are typically not linear (i.e. as screw speed increases rate out increases proportionally over the full range of the screw speed). Depending on the handling characteristics of the feed material as the screw speed increases over 100 RPM (on a single screw feeder) the feed rate output decreases.
