Description

TThe modular Hydroscrew 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. All types are available with ATEX, zone 22 certification.

Function

The light-duty version, CA-L, is mainly used to convey powders or granular materials in the production of pet-food, in the plastics industry, and in soap, washing powder and detergent processing. The medium-heavy-duty version, CA-P, is mainly used in animal feed milling, in wood processing, in the chemical industry, and in environmental technology for both municipal and industrial applications. The extra-heavy-duty version, CA-E, is mainly used in the cement / lime /gypsum, as well as in the mining industry. According to the application various types of screws, inlet and outlet spout models are available.
