Screw conveyorsPipe and trough screws

Zuther screw conveyors offer maximum flexibility and efficiency in bulk material conveying. Whether as a trough or tubular screw – the system has a modular structure and is designed for numerous applications: From normal connecting screws, screw discharge trays, dosing and wetting screws to vertical conveyors and insulated versions for temperature-sensitive products. For particularly poor-flowing bulk materials, our screws are also available as spiral screws. Our screws cover a performance spectrum of up to 600 mm in diameter.

Thanks to the various material options – galvanised, painted or stainless steel – and numerous wear linings, the screw conveyors can be optimally adapted to specific requirements. The right sealing solution is available for every application: in addition to proven systems such as the stuffing box, we also offer innovative technologies such as the SHA Easy Gasket seal. This relies on a static-dynamic double contact surface seal that ensures absolute sealing with minimal and constant frictional resistance. The low resistance not only reduces energy consumption but also minimises the generation of frictional and thermal energy – a decisive advantage for the efficiency and longevity of the system.

On request, Zuther also supplies screw conveyors as a complete solution including suitable components: from butterfly valves, transition flanges and sleeve connections to individual connection geometries – everything from a single source, precisely matched to each other. Generous inspection openings also make maintenance and cleaning easier – even under harsh operating conditions.

The screws are used in a wide variety of areas: Aggregates such as concrete, lime, asphalt or gravel, animal feed, aggregates, grain, granulates and a wide variety of industrial solids. Suitable solutions are also available for abrasive or hygroscopic media – including ATEX-compliant designs.
