ES - Cement Screw Conveyor

Description and working principle

In over thirty years the ES-type Screw Feeder has become a synonym for cement feeding in concrete batching plants all over the world. In this period WAM® have supplied more than 150,000 units which have been operating ever since, the very first one still running with its original screw. After the turn of the new millennium it is hard to find a batching plant manufacturer anywhere in the world who would not appreciate the unrivalled technical features and quality of the ES. Apart from cement, ES-type Screw Feeders are nowadays also used for filler and other materials similar to cement.

Basically the ES is an offspring of the TU series. The unique design of its maintenance-free intermediate hanger bearings and end bearing assemblies c/w splined shaft couplings, as well as drive units with incorporated shaft sealing unit and its widely appreciated ball-jointed universal inlets and outlets set new standards in the industry. Although some have tried to copy the ES, WAM® have been wise enough to continually invest into further industrialization of this product, and there is no end in sight yet.
