Screw conveyors or screw feeders as they are also refereed to, work by using a rotating blade to push objects along a pipe, either horizontally or at a slightly angle.
The items and materials moved depend on the size of the conveyor but mostly tend to be small, fine materials. Liquids and water can also be used in these conveyors, and this makes them unique from other conveyor systems. The speed depends on how fast the blades are rotated, the angle the conveyor is working at and the materials being pushed through. 3DI Equipment has a great selection of used, unused and reconditioned screw conveyors and feeders that produce great results.
