Following a fire that had destroyed the Eddy Current Separation (ECS) system at Evraz Recycling Plant, Tesco was asked to repair the damage and replace the necessary electrical systems. The ECS is based on the use of a magnetic rotor with alternating polarity, spinning rapidly inside a non-metallic drum driven by a conveyor belt. As non-ferrous metals pass over the drum, the alternating magnetic field creates eddy currents in the non-ferrous metal particles repelling the material away from the conveyor. While other materials drop off at the end of the conveyor, the non-ferrous metals are propelled forward over a splitter for separation. Tesco was responsible for the wiring in the power supply and controls for this critical process.
