Non-ferrous metal separator SWP-26B


Non-ferrous metal separator SWP-26B

Eddy current separator (SWP 26B)

The SWP-26B type eddy current separator is designed for automatic separation of non-ferrous metals from bulk or crushed materials. The SWP-26B separator recovers aluminium, copper, magnesium, zinc, silver and other valuable non-ferrous metals with a grain size above 1 mm with high efficiency. In addition, the separator cleans secondary raw materials such as plastics and glass from non-ferrous metals.

The SWP-26B non-ferrous metal separator is reliable, very durable and designed for continuous operation. The separator is characterized by the highest metal separation efficiency. The powerful neodymium permanent magnets used in the polar wheel have high coercivity, which makes them difficult to demagnetize. This makes the eddy current separator have a long service life.

Principle of operation of the non-ferrous metal separator

The operation of the non-ferrous metal separator is based on the principle of magnetic induction. A magnetic rotor rotating at high speed creates a high frequency alternating magnetic field that induces strong eddy currents in metals. Due to the flow of current in non-ferrous metals, a secondary magnetic field is created that opposes the magnetic field of the rotor. The interaction of these fields leads to the creation of the Lorentz repulsive force, which counteracts the force of gravity. The resultant force pushes the metal out of the stream of transported material. The SWP-26B separator is characterized by a high-frequency magnetic field ensuring the highest separation efficiency of very fine metals such as aluminium, copper, magnesium, zinc and silver.
