Description

The modular Hydroscrew Trough Screw Conveyor system is highly versatile. CX Screw Conveyors are manufactured in stainless steel with a suitable surface finishing grade appropriate for the application. The fabrication of the troughs is carried out on machines that guarantee perfectly smooth surfaces due to which material residue is reduced to the minimum. CX Trough Screw Conveyors are made up from a U or V-shaped trough that is equipped with at least one outlet spout, an end plate at each trough end, helicoid screw flighting welded on a centre pipe with a coupling bush at each end, two end bearing assemblies complete with adjustable shaft sealing unit, a number of intermediate hanger bearings depending on the overall length of the screw conveyor, and bolted trough covers. Furthermore, CX Trough Screw Conveyors are equipped with a gear motor that suits the application.
Depending on the material to be handled CX Trough Screw Conveyors come in a light or medium-heavy-duty design.
Both types are available with ATEX, zone 22 certification.

Function

The CX Modular Trough Screw Conveyor System offers a variety of solutions for conveying powdery or granular materials. CX Screw Conveyors are suitable for applications in which any contamination of the conveyed material has to be strictly avoided and in which absolute cleanliness and perfect resistance to corrosion is required.
In particular, CX Screw Conveyors are used in environmental technology, in flour and animal feed milling, in food processing and packaging, for plastics and chemicals, as well as in the pharmaceutical industry.
