Description

The modular CAO Tubular Screw Conveyor system is highly versatile offering numerous solutions for conveying powdery or granular materials. CAO Screw Conveyors are manufactured from carbon steel with suitable surface finishing. They consist of a tubular trough equipped with at least one inlet and outlet spout, an end plate at each tubular 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, and a number of intermediate hanger bearings depending on the overall length of the screw conveyor. Furthermore, CAO Tubular Screw Conveyors are equipped with a gear motor appropriate for the application.
Depending on the material to be handled, CAO Tubular Screw Conveyors come in a light or medium heavy-duty design.
Both versions are available with ATEX, Zone 22 certification.
