Protecting Your Eddy Current Separator Against Ferrous Fines

Ferrous fines accumulation on eddy current separator rotor

Did you know:

  • Ferrous fines can remain affixed to an eddy current rotor indefinitely, heating up and damaging the belt and rotor?
  • Crossbelt magnets and magnetic pulleys cannot remove ferrous fines because magnetic strength and magnetic field distance is too great.
  • A rare earth top-fed drum magnet is required for ferrous fines removal, typically fed by a vibratory conveyor.
  • An eccentric rotor provides an additional degree of protection, but is no substitute for magnetic removal.

The Bottom Line

Proper ferrous fines removal extends rotor life, reduces belt replacement costs, and maintains peak separation efficiency.
