A review of granular flow in screw feeders and conveyors
A screw feeder is used to control the flow rate of bulk material from a bin or hopper. Among screw feeders, single screw feeders are most commonly used. In some literature, screw conveyors flooded with bulk solid, under some operating conditions are treated as screw feeders [3, 8, 12]. Screw conveyor is also called worm conveyor [36].

Design Considerations for an Efficient Volumetric Screw Feeder
Note 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.
