Description
A screw conveyor uses a rotating helical screw blade (flighting) within an enclosed trough or tube to move bulk dry materials horizontally, vertically, or at an incline. The screw rotation propels material through the conveyance path at a controlled rate. Screw conveyors can be designed as tubular, shaftless, paddle, or U-trough configurations, depending on the application and material characteristics.
They handle a wide range of materials—such as grains, powders, pellets, powders, and food products—with capacities adjustable through variations in screw diameter, pitch, speed, and trough inclination. These conveyors offer a compact design, easy installation, complete enclosure for dust prevention, and seamless integration with bins, hoppers, feeders, or other downstream equipment. Custom options include variable-speed drives, rugged bearings, food-grade construction, and detachable covers for ease of cleaning.
