WAM Trough Screw Conveyors

WAM Trough Screw Conveyors

The modular WAM Trough Screw Conveyor system is highly versatile, offering multiple solutions for conveying powdered or granular materials. The light-duty version, WAM-CAL, is often used to convey materials used in the production of pet food, plastics, soaps, washing powders and detergents. The medium heavy-duty option, WAM-CAP, is mainly used in animal feed milling, wood processing, and chemical manufacturing. The extra heavy-duty version, WAM-CAE, is most often used in cement, lime and gypsum processing as well as in the mining industry. To meet the needs of your application, various types of screws and inlet and outlet spouts are available.

WAM Trough Screw Conveyors are manufactured from carbon steel with suitable surface finishing. They are made up of a U or V shaped trough equipped with at least one outlet spout, and end plate at each trough end, helicoid screw flighting welded on a center pipe with coupling bush at each end, two end bearing assemblies complete with shaft seal, a certain number of intermediate hanger bearings depending on the overall length of the screw conveyor, and bolted trough cover sections. They are equipped with a gear motor appropriate for the application.

Depending on the material to be handled, WAM Trough Screw Conveyors come in a light, medium-heavy, or extra heavy duty design. All types are available with AREX, Zone 22 certification.
