Hundreds of thousands operating worldwide

In over four decades the ES-type Screw Conveyor has become a synonym for cement feeding and conveying in concrete batching plants all over the world. In this period WAM has supplied more than half a million units. Today it is hardly possible to find a batching plant manufacturer anywhere in the world who would not appreciate the unrivalled technical features and quality of the ES.

As a specialised version of the modular TU Screw Conveyor System, ES Screw Conveyors and Feeders are manufactured from carbon steel with suitable surface finishing and powder coating. They are made up from a tubular trough equipped with at least one inlet and outlet spout, a welded flange at each tube end, helicoid screw flighting welded on a centre pipe with coupling bush at each end, two end bearing assemblies complete with self-adjusting shaft seal (one of the bearing assemblies is integrated into the drive unit), and a number of intermediate hanger bearings depending on the overall length. ES Screw Conveyors and Feeders are equipped with a gear motor that suits the application.
