(DOC) Designing of Screw Conveyor
The purpose of a screw conveyor is to transfer product from one point to the next. Screw conveyors are always control fed at the inlet by another conveyor or metering device. Rotary valves, screw feeders, belt conveyors, grinders, or even other screw conveyors typically are connected to the inlet of a screw conveyor.

force on the screws and creates frictional resistance. As a result, additional torque is required to start and operate a screw feeder when compared to a screw conveyor. Special consideration is required when designing screw feeders. The starting torque requirements of screw feeders can be as much as 2-1/2 times the demand running torque.
