Screw Conveyor vs. Screw Feeder - Blog | Purvis Industries

Screw Feeders: Designed to meter bulk materials and are typically located at the beginning of a process. The capacity or feed rate of the conveyor system can be accurately controlled with screw feeders. The inlet of a screw feeder is always flood loaded (100-percent full) and typically it will be mounted directly under a hopper, a bin or a silo.
