What is an Eddy Current Separator?
Eddy current separators utilise high-frequency alternating magnetic fields to induce eddy currents in conductive materials. These currents generate opposing magnetic forces that repel non-ferrous metals, effectively separating them from waste streams.
The technology is based on proven electromagnetic principles discovered by Léon Foucault in 1855 and refined over decades of industrial application. Modern separators achieve exceptional purity levels whilst maximising valuable material recovery.
The Science Behind LONGi’s Eddy Current Technology:
- Magnetic Field Generation : High-speed rotating magnetic rotors create rapidly changing magnetic fields within the separator drum.
- Eddy Current Induction : Conductive metals like aluminium, copper, and brass develop circular electrical
- currents when exposed to these fields.
- Repulsion Force Creation : The induced currents generate opposing magnetic forces that physically repel metals away from non-conductive materials.
- Optimised Separation : LONGi’s design optimises magnetic field strength and rotor speed for superior separation performance and maximum recovery rates.
