virvelstrømseparator
A virvelstrømseparator, also known as an eddy current separator, is a non-contact sorting device used to separate non-ferrous metals from other materials. It operates based on the principle of electromagnetic induction. When a stream of mixed materials passes through a rapidly rotating magnetic field, eddy currents are induced within any conductive materials, such as aluminum or copper. These induced eddy currents generate their own magnetic fields, which oppose the primary magnetic field. This opposition creates a repulsive force that pushes the conductive materials away from the non-conductive materials.
The core of a virvelstrømseparator is a high-speed rotor containing powerful permanent magnets or electromagnets. This
Virvelstrømseparatorer are widely employed in various recycling and waste processing applications, including the separation of aluminum
