Screw Conveyor

Screw conveyors, are industrial equipment used in transporting bulk quantities of granular solids (e.g., powder, grains, granules), semi-solids, liquids, and even non-flowing materials from one point to another. They uphold high operational efficiency by eliminating the need for the workers to manually move around loads. Screw conveyors primarily consist of a rotating screw shaft that is installed within a trough. As the screw shaft rotates, the material moves linearly. They can be designed to provide horizontal, vertical, and inclined travel paths.

Several types of screw conveyors are designated to handle a specific material behavior. Bulk materials may be abrasive, non-free-flowing, fluidizing, hygroscopic, or hazardous. The products handled by screw conveyors are the likes of cereals, fertilizers, animal feeds, ash, gravel, cement, and solid wastes.
