The modular CA Trough Screw Conveyor system is highly versatile offering numerous solutions for conveying powdery or granular materials. CA Screw Conveyors are manufactured from carbon steel with a suitable surface finishing. They are made up from a U or V-shape 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 shaft sealing unit, a certain number of intermediate hanger bearings depending on the overall length of the screw conveyor, and bolted trough cover sections. Furthermore, CA Trough Screw Conveyors are equipped with a gear motor that suits the application. Depending on the material to be handled CA Trough Screw Conveyors come in a light, medium-heavy, or extra-heavy-duty design.
