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.
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.

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.
