Screw conveyors are highly efficient systems for transporting bulk materials, featuring a rotating spiral screw contained within a tubular casing or trough. As the screw rotates, it effectively moves dry or semi-dry bulk materials from one location to another, accommodating a diverse range of substances, including powders.

Produced by leading manufacturers, tubular and trough screw feeders provide versatile solutions for feeding and conveying various materials such as powders and granules. They are built from durable carbon steel or stainless steel, with appropriate surface finishes to enhance longevity, and are designed for medium to heavy-duty applications.

The design incorporates a tubular or trough structure that includes at least one inlet and outlet spout, welded flanges at both ends, and helicoid screw flighting attached to a central pipe with coupling bushes on either side. Each conveyor is equipped with two end bearing assemblies featuring self-adjusting shaft sealing units, and multiple intermediate hanger bearings are added based on the overall length of the conveyor.
