Eddy Current is a circular electric current that occurs in conductors when the magnetic field changes due to the law of induction. Eddy current flows in a closed loop in planes perpendicular to the magnetic field.

Diamagnetic materials are substances such as Copper, Aluminium, Bismuth, Diamond, Silver, Lead, and Silicon, which can be magnetized by any magnet in the opposite direction to the magnetic field lines while in the magnetic field of that magnet.

Eddy current separation is an effective separation method used to separate non-ferrous diamagnetic metals from non-metallic wastes. The Magnetic Drum, which consists of high-power permanent magnets, is rotated at high speed and creates an eddy current, creating a changing magnetic field. When metals such as copper and aluminium are in the eddy current, they create a repulsive force and, with the effect of centrifugal force, the non-metallic material falls freely while throwing the non-magnetic metal to a longer distance, allowing it to be separated. Belt speed, size, volume and weight of metal, magnetic sensitivity, blade setting are major factors in separation.

It consists of a non-ferrous rotating empty external drum, an independent high-speed rotating permanent magnetic rotor inside the empty drum, a drive and a belt conveyor. The outer drum shell, made of non-metallic composite material, rotates at conventional belt conveyor speed. The alternating pole Magnetic rotor (Drum), manufactured from Neodymium Magnets, rotates at much higher RPM than the outer shell. Ferromagnetic materials holding on to the magnetic drum surface get hot due to eddy current, which may cause damage or abrasion of the tape or magnets. For this reason, it is recommended to separate the product from ferrous metals with magnetic separators before feeding the product to the Eddy Current Separator.

Our Eddy Current Separators can separate aluminium parts with a minimum size of 30x30x0.5 mm and above, and copper parts of 20x11x2 mm and above.

Eddy Current Separator Magnetic Drums are produced locally in our Mıknatıs R&D İzmir factory.
