Mechanical Conveying / Screw conveyors
Screw Conveyors for economical and flexible conveying
Screw conveying is the answer for silo reclaiming, material transport between process devices and moist material conveying. With Kopar screw conveyors, you reliably transport a wide range of bulk materials for various applications in several industries.
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.
Cooling screw conveyors for compact cooling
A screw conveyor can also be implemented as a cooling conveyor, where the material is transported and cooled in the same device. A cooling screw conveyor is a good solution when the material flow is relatively small and the cooling capacity does not need to be high. Typically, the solution is suitable for applications where the capacity is moderate and the screw diameter is less than 500 millimetres.
The key advantages of a cooling screw conveyor include full gas-tightness and a compact design that is easy to fit even in confined spaces. The investment cost is typically lower than, for example, rotary cooling solutions. The rotor can be implemented with either a traditional continuous screw flight or From the KRC radiator with a rotary laparoscope. The structure is always chosen according to the material to be processed and the process requirements.
As with all cooling solutions, the choice is an optimisation of the whole. For larger capacities or more demanding applications, for example, a KRC chiller offers better maintainability and lower operating costs. We help you choose a solution that meets the real needs of your process, both technically and economically.

Technical specifications
A screw conveyor moves granular materials using a rotating helical screw blade, generally within a round tube or U-shaped 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.
