Durable Screw Conveyor for Conveying Granular Material

As a critical piece of equipment in the material handling field, the durable screw conveyor features a unique tubular design and high-efficiency performance, making it well-suited for the bulk material handling industry.

Its tubular structure effectively minimizes material spillage, while the spiral blades and drive unit work in tandem to ensure stable material conveyance. Additionally, the integrated control system enables precise operation control and real-time fault alarming, providing reliable support for continuous industrial production.

Working Principle of the Screw Conveyor

When the screw shaft rotates, the materials, constrained by their own gravity and the frictional force between them and the trough wall, cannot rotate synchronously with the spiral blade. Instead, they move forward along the bottom of the trough under the pushing force of the blade—this movement is analogous to a non-rotating nut moving translationally along a rotating screw.

The primary driving force for the materials’ forward movement comes from the axial component of the force exerted by the rotating spiral blade. This force drives the materials to move upward and forward along the tangential direction of the blade, thereby achieving continuous conveyance of materials.
