Shredder Light Fraction – Fines Upgrading

Application

A fines separation and upgrading system was added after the final SLF discharge conveyor on an existing shredder downstream.

A trommel was utilised to separate the 0-20mm fraction from the total material stream.

The fines fraction was processed through a Steinert FinesMaster unit incorporating a rotary drum magnet, belted head drum magnet and fines eddy current separator to provide four separate products:

  • High grade ferrous
  • Low grade ferrous / magnetic dirt fraction
  • Mixed non-ferrous metals
  • Residual fines light fraction

All separated fractions were chuted into product bays under the support structure. The >20mm oversize fraction from the trommel was transferred via conveyors to a stockpile.
