Conveying mechanisms & discharge devices


When it comes to ensuring excellent availability and operational safety in dedusting plants, discharge devices and conveying mechanisms are just as crucial as fans and filter systems. For decades now, Scheuch has been producing rotary valves, conveying screws, dosage devices and pendulum flaps in-house.

Our extraction, filtration and material discharge devices therefore form a single unit consisting of technically mature and reliable components. All transport devices are engineered for explosive atmospheres as defined in different codes and regulations.

Our Solutions

Rotary valves


Discharging and locking with rotary valves

Rotary valves (sometimes called airlocks) are used to discharge dust, chipboard shavings and fibrous conveyed goods, and as shut-off devices. A range of designs are available to suit various requirements, with throughput volumes to accommodate every case.

Scheuch rotary valves can also be delivered explosion pressure shock proof and as type-tested ATEX-protective systems (ignition and flame penetration resistant) for explosion decoupling purposes.

When it comes to ensuring availability and operational safety in dedusting plants, discharge and conveying mechanisms are just as crucial as fans and filter systems. Extraction, filtration and material discharge devices thus form a single unit.


Pneumatic conveying

Safe and reliable transport of material

Pneumatic systems are extremely safe and reliable and – because they contain hardly any mechanical or moving parts – are virtually maintenance-free and non-wearing.

There are generally two basic designs: the low-pressure or low-density conveying system, which uses a radial fan as the compressor, and the high-pressure or high-density conveying system, which uses a rotary piston blower. High-pressure systems are ideal for use with conveying quantities of 1 to 100 t/h, conveying systems of up to 1500 m in length, and nominal widths between 88 and 500 mm.


Screw conveyors

For individual requirements

Tube-type and trough screws are used to continuously transport bulk materials, at throughput volumes of 2 to 500 m³/h and with screw diameters between 200 and 1,000 mm.


Metering devices

Newly Developed Metering System Improves Efficiency

Scheuch has developed a new metering unit (feed tank) that is significantly more efficient, especially when used in high-pressure conveyor systems. The increase in efficiency is achieved by optimising and simultaneously adjusting operation for the maximum operating quantity. Even the material density is automatically adjusted to match the previously set tonnage, making it possible to transport up to 25 percent more material with the same energy requirements.

This system can also mix different materials, e.g. chips and sawdust in order to reduce fluctuations in material density.
