Magnets that Separate Aluminium and Copper from Waste!
02/09/2009 - Eddy-current Separators help solve recycling problems
When a non-ferrous metal item is passed through a magnetic field, eddy-currents are generated within the item. These small electric currents, in turn, induce a magnetic field around the item.
This magnetic field can be used to repel the non-ferrous metallic piece. The principle is used in Longi Eddy-current Separators to remove aluminium, copper and other non-ferrous metals from municipal and other waste.
A suitable Longi magnet is used prior to the Eddy-current Separator to remove ferrous items first as they will cause damage to the eddy-current system. Longi Magnet Co Ltd is able to supply complete systems for recycling including conveyors, magnets and Eddy-current Separators and is represented in Australia by Serpent and Dove® Pty Ltd.
