Screw Feeder - an overview ScienceDirect Topics

Screw feeders tend to have a pulsating effect from the screw flight, regardless of whether the screw is an open flighted helix or a solid screw. As the screw flight passes the discharge opening, nil or minimum material exits the feeder. Typically two-thirds of the material exiting the feeder per screw revolution is delivered in the first one-third of the screw rotation, while the other one ...
