Our screw conveyors are an economical method for elevating and conveying on-site. All our conveyor systems are easy to maintain and customizable. If there is a sudden need for maintenance, our engineers ensure that the production is not halted for long.

We have decades of experience using screw conveyors in extremely challenging applications, i.e. in precise feeding, silo reclaiming or moist material conveying. We have noticed that it is possible to overcome all these challenges with proper planning and sound engineering.

When we design a custom screw conveyor according to your needs, we keep in mind the conveyed materials, chemical resistance, material load volume (bulk density), frequency of use and any other necessary features, requirements, and processes for the conveyor to perform. With these details, we can customize a screw conveyor for your needs.

Technical specifications

A screw conveyor moves granular materials using a rotating helical screw blade, generally within a round tube or U-shape frame.
Screw conveyors offer high flexibility layout-wise as you can install the conveyors in different inclination angles.

Built to last

Frames and screws can be manufactured of carbon steel, acid-resistant steel, wear-resistant steel, or stainless steel. The choice depends on the structural needs of the conveyed material and possible chemical reactions between materials.

Versatile options

Screw conveyors can be used in various applications including silo reclaimers or steady dosing feeders.
