The JOEST J-Flow is a compact gravity separator with an internal air circulation system, specifically designed for the reliable separation of light fractions from free-flowing bulk materials. It is primarily used in metal recycling applications – such as ASR (Automotive Shredder Residue), SLF (Shredder Light Fraction), or SHF (Shredder Heavy Fraction) systems – and upstream of optical sorters, where it effectively removes contaminants like fluff, films, textiles, or foam materials, significantly improving the quality of downstream metal fractions. Thanks to its integrated airflow system and compact design, the J-Flow can also be easily retrofitted into existing plants. It operates efficiently with particle sizes between 10 mm and 120 mm, and is also capable of handling elongated parts up to approx. 300 mm. For optimal results, pre-sorting by grain size classes – e.g. 10–50 mm or 50–120 mm – is recommended.
