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. A very short payback period can be achieved.

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