The modular CX Trough Screw Conveyor system is highly versatile. CX Screw Conveyors are manufactured from stainless steel with surface finishing grade suitable for the application. Fabrication of the troughs is carried out on machines ensuring perfectly smooth surfaces which is why material residue is reduced to the minimum. CX Trough Screw Conveyors are made up of a U or V-shaped trough equipped with at least one outlet spout, an end plate at each trough end, helicoid screw flighting welded on a centre pipe with coupling bush at each end, two end bearing assemblies complete with adjustable shaft seal, 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 appropriate for 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.
