Screw Conveyor

Screw conveyor is one of the most widely used conveyors. Screw conveyor is used to transport bulk materials from one position to another. Screw conveyors can be built in a variety of sizes, lengths, configurations and materials.

Screw conveyor can be used for light, free-flow and non-abrasive block materials.



1.The screw conveyor can be loaded and unloaded at any point on its transmission line
2.Fully sealed for conveying easy to fly, hot, strong smell of materials, reduce the harm to the surrounding environment.
3.Relatively simple structure, low investment cost, stable operation, simple and convenient maintenance, compact product size, small section size, less occupation for the work site.
4.Screw conveyor process layout is flexible, can be elevated, ground or pit layout, can be horizontal or climbing installation.
5. Carbon steel, stainless steel, wear-resistant alloy, and other building materials can be selected for conveying different materials.
6.Screw conveyor adopt flange end bearing assemblies, which can protect against material infiltration by shaft seals.
7. The surface of screw blade after hardening treatment, its hardness and wear resistance of are twice higher than that of the ordinary blade, and the hardness of the outer edge is up to HB240.

Working principle

The working principle of the screw conveyor is that the rotating screw blade pushes the material for the screw conveyor.
The force that can not make the material rotate with the screw conveyor blade is the gravity of the material itself and the friction between the screw conveyor shell and the material.
