Multotec Eddy Current Separators separate non-magnetic (non-ferrous) metals from your material feed. They use the different electrical conductivities of ferrous and non-ferrous particles in shredded material to remove the non-metallics, separating non-ferrous metals such as copper and aluminium from other conveyed material.
Each non-ferrous metal has its own properties, which will be repelled from the conveyor with varying force; the different types of non-ferrous material can therefore be efficiently separated.
Multotec Eddy Current Magnetic Separators purify large bulk streams and can handle high capacities. It separates and carries away non-ferrous metals continuously and automatically.
Application examples include:
Like any current flowing through a conductor, an eddy current will produce its own magnetic field. Eddy currents flow in closed loops within conductors, perpendicular to the magnetic field.
The Eddy Current Magnetic Separator divides the material through the use of a magnetic rotor, with alternating polarity, rotating at high speeds. The non-ferrous metal passes over the rotor and the alternating magnetic field creates an eddy current in the non-ferrous metal repelling the particle away from the conveyor, while the other material remains on the conveyor.
