A screw conveyor is a machine designed to convey powdered or granular substances by rotating a helical blade, which acts as a screw.
The operating principle is relatively simple: as the screw rotates, the material between its blades is pushed forward by the rotation and conveyed along the trough. This mechanism allows for the efficient transportation of powdered or granular substances.
Screw conveyors find applications in various places such as food factories, chemical plants, pharmaceutical factories, construction sites, and agriculture. They consist of components like the screw shaft, drive unit, inlet, and outlet, among others. Their features include a simple structure, high versatility, enclosure, ability to convey in an inclined direction, and relatively low installation cost.
