Magnet Drum Separator img

STAR TRACE Eddy Current Separation devices are an effective way of removing non-ferrous metals from other products. Application such as aluminum cans from municipal waste, aluminum flakes from shredded PET, brass and aluminum from foundry sands, and metals from shredded automobile scrap, other metals such as lead can also be removed. For successful non-ferrous separation, a magnet should be installed prior to an Eddy Current Separator.
Eddy Current Rotor:

STAR TRACE Eddy Current Rotor uses an alternating magnetic field to produce electrical currents in conductive metal. The electrical current generates its own magnetic field around an object which opposes the magnetic field from the Eddy Current. This repulsion diverts the object from the product stream. Mass, conductivity and density influence the force and distance an object will repel.
Working of Eddy Current Separator:
Eddy current separation 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.
Eddy Current Separation System:
STAR TRACE Eddy Current Separation System encompasses all the equipment above necessary to separate non-ferrous metals and adds ferrous metal separation equipment. It is important to remove ferrous metal prior to exposure to the Eddy Current Separator. Ferrous metal is attracted and held by the strong magnetic force. The ferrous metal will heat up and could burn holes in belt and cause significant damage to the Eddy Current Rotor.
