Screw Conveyors

Silo reclaiming, material transport between process devices or moist material conveying, screw conveying is the answer

With Kopar screw conveyors you transport reliably a broad range of bulk materials for a variety of applications in several industries. Our screw conveyors are an economical method to do the elevating and conveying on site. We highly value that all our conveyor systems are easy to maintain and customizable. If there is a sudden need for maintenance, our engineers make sure that the production is not halted for long.

Got a custom need for screw conveying? Challenge accepted

We have decades of experience using screw conveyors also in very challenging applications ie. in precise feeding, silo reclaiming or in moist material conveying. We have noticed that all these conditions and challenges can be overcome with proper planning and good engineering.

When we design a custom screw conveyor according to your needs, we keep in mind what type of materials are moved, 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 are capable to satisfy your needs and customize screw conveyor for you.

Technical Specifications

A screw conveyor uses a rotating helical screw blade, normally within a round tube or U-shape frame, to move granular materials. Screw conveyors offer high flexibility in layout-wise as the conveyors can be installed in different inclination angles.

Frames and screws can be manufactured of carbon steel, acid resistant steel, wear resistant steel or stainless steel. The usable material is dependent on the conveyed material to match the structural needs or possible incompatibilities with chemical reactions with materials.

Typical features of Kopar’s screw conveyors:

  • Capacity 0 – 200 t/h
