A drag conveyor and an auger (or screw conveyor) are both used in heavy industries like mining for material handling, but they operate differently and are suited to different tasks. Drag Conveyor: This conveyor uses a series of flights (attachments) that are dragged through a trough, moving bulk materials such as coal, minerals, or aggregates. The material is conveyed by the dragging action of the flights along the trough, typically resulting in low material degradation. Drag conveyors are well-suited for moving large volumes of material over long distances with minimal spillage. Auger (Screw Conveyor): An auger consists of a helical screw blade (flight) rotating within a tube or trough to move materials. This method is ideal for handling materials like grains, cement, or small aggregates but tends to cause more material degradation due to the shearing action of the screw. Augers are typically used for shorter distances or vertical transport, where precision and consistency in material feed are more critical.
