JOEST and its American partner are supplying a complete processing system in the USA for the recovery of fine metal with a grain size smaller than 12 mm.

JOEST is supplying the screening and separation technology for this patented processing system, including long-part separators, flip-flow screens, air separators and three-way separation tables. The purpose of the system is to recover fine metals and separate light from heavy metals.

The feed material consists of the fine fractions of crushed cars without the magnetic portion. These are called “ASR fines” in the USA and “shredder heavy fraction / shredder light faction” in Europe. First of all, long copper cables are separated from this material using the long-part separator. Subsequently the 0–12 mm fraction is screened at approx. 4 mm in the JOEST Flip-Flow Screen TOPCILLA. Each fraction (0–4 and 4–12 mm) goes to one of the four K-Sifters with separation tables.

The K-Sifter is installed above the aspiration hood of the JOEST separation table for pre-separation of very light products. The feed material is fed to the K-Sifter via a resonance conveyor or dosing feeder. The resonance conveyor is used to distribute the product over the entire width of the sifter, and also prevents additional air from flowing into the sifter thanks to its rubber curtains.
