  • What is a Screw Feeder?

    A screw feeder is a device used in various industries to accurately meter or feed amorphous or loose grained materials from one part of a process to another Screw feeders are very similar to screw conveyors in their basic structure, both of which are based on the principles of the Archimedean screw for their operation A screw feeder is capable of delivering dense slurries and dry granularScrew 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 twothirds of the material exiting the feeder per screw revolution is delivered in the first onethird of the screw rotation, while the other oneScrew Feeder an overview | ScienceDirect TopicsScrew feeders are used with product causing no or medium abrasion but should be avoided with products causing high level of abrasion ; the screw rotating in the product, is indeed very sensitive to abrasion phenomena A screw fitted directly to a hopper upstream is often referred in the literature as screw feeder while the equipment alone is often referred as screw conveyor The screw conveyorScrew Feeder Screw Conveyor Auger Engineering Guide
