Recovery of tiny fragments of Ferrous and Non-Ferrous Metals from Shredder Residue

Fines and ultra fines which are generated by screening at approx. <20 mm (3/8”) make up 20-40 % of the total weight of the Automotive Shredder Residue (ASR). They contain significant quantities of recoverable ferrous and non-ferrous metals. The revenue potential of ASR fines is often underestimated.

SICON has integrated into European Shredder Residue Processing plants the total metal recovery already since 2005. With FinesTuning® SICON has developed a flexible system that reliably separates over 99 % of separable NF-metals contained in ASR fines. The multi-step magnetic separator system is the first of its kind to guarantee highest metal recovery; it consists of two magnetic drums with different adjustable magnetic field strengths. The first pass generates a clean ferrous fraction. The light-magnetic dirt and fines are then removed by a second drum without any loss of stainless steel in the magnetic dirt.

Tests have shown that the SICON FinesTuning® leads to higher recovery rates and therefore is also recommendable as replacement for existing, less efficient systems. FinesTuning® is available in widths of 500, 1000, 1500 and 2000 mm (20”, 40”, 60”, 80”) and comes with various features and options such as adjustable drum speeds, belt-runempty- technology, belt-exchange-system and many more.

SICON install its FinesTuning® unit both in new systems and in existing systems with throughputs of up to 30 mt/h. A very short payback period can be achieved.

FinesTuning® unit usually pays for itself within 9 to 21 months, depending on the throughput rate.

FinesTuning® - Your benefits at a glance

  • Highest Metal Recovery
  • Short Payback Period
  • Space Saving Design Concept
  • Processing system for fine fractions < approx. 20 mm of the shredder light, shredder heavy fraction or (A)SR
  • Multi-stage Fe-separation to obtain a clean Fe-fraction and separation of a residual magnetic waste fraction
  • Complete separation of non-ferrous metals by means of a special eddy current separator for finest fractions, which separates non-ferrous metals down to a grain size of 0.2 mm
  • Throughput  from 2 to 30 mt/h
  • Optional: extension by further metal processing steps, e.g. copper separation from the recovered Zorba fraction
