Screw conveyor

Screw conveyors: Robust conveyor technology from RGS GmbH

The principle of the screw conveyor is very simple: Friction and gravity affect the transported bulk material at the “screw trough”, thus transporting the material further up to the desired destination. Screw conveyors are particularly well-suited for the transport of granulates, powdery substances and classic bulk materials as well as liquids.


With RGS GmbH screw conveyors, it is possible to transport material horizontally, vertically as well as over gradients at very high conveyor rates.

When should I use a screw conveyor?

Screw conveyors are particularly useful when you need to transport abrasive, aggressive bulk material on a permanent basis. In such cases, the screw conveyor is a particularly durable solution with little wear.

It offers a very low-maintenance and less failure-prone conveyor system that convinces customers with its high efficiency and low maintenance costs.


The high conveyor rate that can be achieved with screw conveyors is often the decisive factor in choosing this type of conveyor technology from the range of RGS conveyor systems.

Low operating costs as an additional advantage

RGS GmbH focuses deliberately on very energy-efficient modules when building the drive system of its screw conveyors and convinces its customers with low energy costs during operation. Using the simple construction of the screw conveyor as the centrepiece of conveyor systems also means that maintenance costs tend to be lower than those of more complex systems. Replacing a screw conveyor once its service life has run out is fast and easy. The spare parts service at RGS GmbH assists our customers quickly and simply.

Upon request, the team at RGS recycling systems GmbH can also carry out the complete maintenance of the screw conveyor.

Individual planning of closed conveyor systems

RGS GmbH in Kirchdorf am Inn not only offers “screw conveyors” as a component but also plans complete conveyor systems : Together with our customers, we develop all the conveyor technology for the screw conveyor. With RGS screw conveyors, you can mix or press bulk material during transport or even extract liquid from the material. Screw conveyors from RGS GmbH also allow for the implementation of dry and cooling processes.


The construction material for the screw conveyor’s transport shaft is selected according to the requirements in the conveyor process. As an independent conveyor technology specialist, RGS GmbH always chooses the best solution for its customers. We develop closed conveyor systems in close collaboration with our customers that take full advantage of conveying with a screw conveyor.

RGS GmbH develops well thought-out conveyor systems including the control system, the conveyor and weighing technology as well as commissioning on site and ongoing service.
