FinesTuning^®

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

Fine and ultrafine fractions generated during the screening of shredder residues smaller than 20 mm account for between 20 and 40% of the total weight of the shredder residues. They contain significant amounts of recoverable ferrous and non-ferrous metals. The economic potential of these fine fractions is often underestimated and can be realized using the SICON FinesTunung.

Since 2005, SICON has been integrating systems for the complete recovery of metals from ultrafine fractions into various European facilities for the processing of shredder residues. With FinesTuning®, SICON has developed a flexible system capable of reliably separating over 99.5% of the recoverable non-ferrous metals from the fine fractions. The multi-stage magnetic separator system is one of the first of its kind to enable a maximum metal recovery rate. It consists of two magnetic drums, each with individually adjustable magnetic field strength. In the first step, the Fe fraction is completely separated. The slightly magnetic residue and the fine fractions are then separated in a second drum without losing the stainless steel from the magnetic residues.

Tests have shown that SICON FinesTuning® leads to higher recovery rates and is therefore also recommended as a replacement for existing, less efficient systems. The new FinesTuning® is available in widths of 500, 1,000, 1,500, and 2,000 mm and offers various functions and options such as adjustable drum speeds, Belt-Run-Empty technology, a belt exchange system, and many more. SICON implements FinesTuning for shredder residues <20 mm in new plants as well as a retrofit for integration into existing plants with throughputs of up to 30 t/h.

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