Schrage vs. Screw conveyors

Screw conveyor
- Require little space
- More cost-effective for very short distances
The principle of operation behind screw conveyors uses the Archimedes screw, which enables the conveyors to move material horizontally, vertically, and at an angle. They are somewhat limited to relatively short conveying distances, as the screw conveyor’s design-inherent trough friction means that the power required to drive them is significantly higher than that required for belt conveyors and bucket elevators.
