Screw conveyors
Scheuch COMPONENTS develops and manufactures screw conveyors for industrial applications. Our specialists support you from the first enquiry through to commissioning, with personal consultation, in-depth process know-how and test facilities for material trials.
Screw conveyors – the right transport systems to suit your needs
Screw conveyors are used wherever a variety of bulk materials have to be transported quickly and safely. Scheuch COMPONENTS offers a wide selection of variants, allowing you to find exactly the right conveyor to meet your specific requirements.
Shaftless screw conveyors
Shaftless screw conveyors transport bulk materials of varying consistency. Unlike conventional screw conveyors, they have no central shaft. This creates a larger conveying cross-section, which also makes it possible to transport damp, fibrous or sticky materials. The screw spiral moves the material within a trough or pipe and can be installed horizontally or inclined, depending on requirements. The design depends on the conveyed medium and the operating conditions.
The following technical data applies:
Throughput volume at 100% fill level: 0.1 – 300 m³/h
Max. conveyed material temperature: 250 °C
Standard nominal diameter: 125 – 500 mm
Custom made screw conveyors
In addition to our standard range, Scheuch COMPONENTS develops and manufactures custom and special screw conveyor solutions, tailored to our customers’ requirements and applications. We offer a range of configuration options for screw conveyors:
Any design of inlet and outlet
Customized wear protection concepts
Stainless steel design
Heat tracing and insulation
Explosion-protected design in accordance with ATEX (Directive 2014/34/EU)
Rotation monitoring
Direct speed control on the screw
High-temperature designs up to 450 °C
Pressure-surge resistant design up to 9 bar
Twin-trough screw conveyors
What is a screw conveyor?
A mechanical screw conveyor is a transport or conveying system that can be used for an extensive range of bulk materials. Screw conveyors are driven by a motor and operated according to the Archimedes screw principle. This means that the element being conveyed is moved by constantly rotating the screw shaft, which looks like a screw.
Since gravity creates friction between the conveyed material and the pipe walls, the material does not rotate with the spiral but is transported instead. To achieve the highest possible conveying rate, the friction on the screw thread should be significantly lower than that on the pipe or trough wall.
In addition to the rotating screw shaft, the screw conveyor consists of a screw thread, a drive unit, an inlet and outlet, and – depending on the design – a conveyor pipe or screw trough.
What are the special features of a screw conveyor?
In contrast to pneumatic suction systems, screw conveyors are usually less expensive, quieter and, most importantly, suitable for shorter distances. The conveying distance can be quite steep (up to 30 degrees difference in altitude), but should be kept as straight as possible.
Advantages of a screw conveyor:
Dust-free and closed conveying process
Specific seal design for the area of application
Ideal drive dimensions
Designed for 24/7 continuous operation
Scheuch COMPONENTS provides screw conveyors up to 13 metres long
Robust design for maximum loads in continuous operation
Flexible system integration using 3D planning
Short delivery times due to largely standardized modular design
What types of screw conveyors are available?
We currently offer three basic types of screw conveyor. They differ in their design, their technical key data and their areas of application.
Would you like to buy a screw conveyor for your operations but are not yet sure which type best suits your requirements? Use the following overview and visit the detail pages for more information on the individual designs:
Pipe screw conveyors: particularly suitable for steep conveying
Trough screw conveyors: easily accessible and low maintenance
Special and custom-made screw conveyors: made to measure for specific project requirements
Areas of application for screw conveyors
Screw conveyors are used wherever bulk materials need to be moved. The main task of the screw conveyor can include shutting off, discharging, dosing or compressing the material.
The materials conveyed can be granular, powdery or viscous and consist of wood, metal or plastic, for example.
Which industries are screw conveyors suitable for?
Screw conveyors are suitable for businesses including agricultural operations, companies processing wood-based materials or metallic materials, recycling centres, chemical and pharmaceutical companies or operations in the animal feed industry.
Our standard screw conveyor designs with a diameter between 200 and 1,000 mm can achieve a throughput volume of 2 to 500 m³/h. Customized and special designs are adapted to your requirements.
Our screw conveyors are produced from high-quality materials, which means that they can be made of stainless, high-strength steels with resistance to attacks if this is suitable for the application. On request, we can also produce screw conveyors in accordance with the ATEX directive and with additional equipment tailored to suit your requirements.
“We enjoy working with our customers to develop the right solution for their individual needs. As a technology leader, our ambition is to always be one step ahead.”
