Eriez says that these are five times stronger than conventional permanent magnets, for stronger eddy currents and separation of non-ferrous materials. Eriez Eddy Current Separators (ECS) remove non-ferrous metallics from plastics, glass cullet, electronic scrap, automobile shredder residue (ASR), boiler bottom ash, spent foundry core sand, municipal solid waste (MSW), co-mingled recyclables, urban wood waste and mixed metals.In operation, these non-ferrous separators utilise permanent Rare Earth magnets to induce eddy currents into non-ferrous metals. This produces repelling forces that separate the non-ferrous metals from non-metallics, providing a cleaner product for further processing. Removal of non-ferrous metals is selective and product loss is minimised.
