Eddy-current separator

The IFE Eddy-Current Separators are used for separating non ferrous metal parts (aluminium, copper, lead) from bulk material of all kinds. Areas of application are, among others, the recovery of non ferrous metals from shredded material, recycling of valuable material and in glass and foundry sand recycling. Is available both as centric system and excentric system. Owing to the particularly strong permanent magnetic field and the high speed of the magnetic rotor, good separation results can be obtained even with small or difficult to separate materials. The material to be separated is transported over the belt conveyor in a layer as thin as possible and gets to the area of the fast rotating magnetic field of the head pulley at the discharge side. This induces eddy currents which build up a magnetic field around each particle of non-ferrous metal, the magnetic field opposing the permanent magnetic field of the magnetic rotor. Therefore a strong impulse is exerted on the parts of non-ferrous metals, throwing these particles off the stream of the conveyed material. Ferromagnetic parts contained in the stream of material are moreover transported with the centric system with the belt conveyor around the head pulley and are thus separated from the stream of material. For good separation results, an even distribution in one single layer with regular sized particles is advisable if there is a greater number of ferromagnetic parts in the stream of material, these should be pre-separated.
