Trough screw conveyors
Individually tailored trough screw conveyors for customer-specific applications
Trough screw conveyors are suitable for all kinds of applications at a variety of process levels. Ideal for collecting and distributing bulk materials, they are also an excellent choice for discharging, compressing and mixing – and can even be used for blocking, decoupling and dosing. Our many years of experience mean we have the in-depth knowledge required to handle an exceptionally wide variety of bulk materials
We work with our customers to pinpoint customized solutions that will suit their exact transportation and distribution needs.
Our product range also includes wear-resistant concepts and explosion-proof design in line with ATEX directive. Scheuch COMPONENTS also offers filter screw conveyors.

What makes a trough screw conveyor so special?
Trough screw conveyors work according to the Archimedes screw principle: their constant turning motion transports conveyed material continuously to various production stations or final filling stages. Among the features that make the trough screw conveyor a standout piece of equipment is the low-maintenance technology it contains and its outstanding reliability.
Trough screw conveyors can be installed in horizontal, vertical or angled positions, which means they can integrate seamlessly into any production process.
What kind of structure does a trough screw conveyor have?
Trough screw conveyors are made up of multiple components, the most important of which are:
- the screw trough
- the screw conveyor
- the drive unit
- the bearings at the shaft ends
- the inlet and outlet
Screw troughs are equipped with either a trough cover or a conveyor pipe, depending on how they are designed. The components that make up the screw conveyor include a screw thread, a drive and outer bearing shaft, plus various sealing elements. The drive is coupled with either a shaft coupling or a chain drive, depending on the requirements of the application.
Which conveyed materials are trough screw conveyors able to transport?
Trough screw conveyors are primarily suitable for transporting powders and granulates. Ideally, pipe screw conveyors should be used to transport liquids.
The materials that trough screw conveyors transport usually have fibrous, semi-moist, granular or dust-like consistencies: this type of equipment is less suitable for handling materials that are coarse or sticky, or cake heavily.
Additionally, the strong force they exert on conveyed materials means that trough screw conveyors are not particularly well suited to transporting highly sensitive goods – of the kind found in the food industry, for instance.
What applications can trough screw conveyors be used in?
Trough screw conveyors are exceptionally versatile: they are just as much at home in grain silos as they are in pellet heating systems and the plastics industry.
Since they contain a screw conveyor that mixes various conveyed materials, trough screw conveyors can also be found in cement production and concrete mixing applications.
Sewage treatment plants and injection moulding systems are more examples of potential applications, as are trench cutting processes and vending machines.
What types of trough screw conveyor are available?
Above all else, the design of a screw conveyor is dictated by the materials to be transported, the filling quantity and the length of the transport process. We can create whichever structure suits your needs – whether that’s a single-shaft system, a double-shaft system or a custom-made screw conveyors. In each and every case, we adapt our trough and pipe screw conveyors to satisfy the exact requirements of our customer, ensuring that they’re a perfect match for the process in question.
