What an Eddy Current Separator Actually Does
An eddy current separator recovers non-ferrous metals — aluminum, copper, zinc, brass — from shredded material after ferrous metals have been removed by a magnet. A rapidly rotating magnetic rotor inside the belt shell induces eddy currents in conductive particles, repelling them forward off the belt while non-conductive material falls normally. Buyers comparing China eddy current separator brands are usually evaluating how well each supplier matches this core physics to their specific material stream.
Tiangong Technology Co., Ltd. (founded 2008) integrates eddy current separators into complete recycling lines built at its 12,000 m² production facility, alongside twin-shaft shredders, granulators and magnetic separation.
Where Eddy Current Separation Fits in a Line
In our TG-EWasteLine 150 E-Waste Metal Recovery Line, the eddy current separator sits after the twin-shaft shredder, granulator and magnetic separator, recovering non-ferrous metals and concentrated metal-bearing fractions from discarded electronics. The TG-ELVLine 300 End-of-Life Vehicle Shredding and Recycling Line uses the same sequence — hammer mill, magnetic separator, eddy current separator and air classification — to turn depolluted vehicle hulks into sorted ferrous, non-ferrous and residue fractions in a single continuous pass. The TG-AluLine 200 Aluminum Scrap Recycling Processing Line applies eddy current separation to remove non-ferrous contaminants before hydraulic briquetting.
Belt Width: Match It to Your Throughput
Belt width determines how much material passes per hour and how thick the bed is. A bed that is too thick buries conductive particles, so they never feel the rotor's field and report to the residue. When comparing brands, ask what belt widths are offered and, more importantly, what feed depth the supplier recommends for your material. For medium-capacity yards, our TG-ScrapLine 150 Integrated Scrap Processing System shows how a 15 t/h line stages shredding, magnetic separation and briquetting around the separation step.
Recovery Rate: What Really Drives It
Recovery rate depends less on the brand name than on these factors:
- Particle size and liberation: conductive particles must be liberated from insulation, rubber or other attachments
- Feed bed depth: thin, even feeding beats raw belt width
- Rotor speed and belt speed ratio: matched to particle size range
- Splitter position: tuned per material mix, not set once
Comparing Brands: Questions to Ask Any Supplier
- Which rotor design and pole configuration do you use for my particle size range?
- What recovery rate do you commit to on a sample of my actual material — and will you run a test?
- How are the rotor and belt serviced, and what is the wear-parts supply situation?
- Is the separator CE-marked and integrated with line-level PLC control and interlocks?
Our equipment is CE-marked, manufactured under ISO 9001 quality management, and lines are delivered with PLC control managing stage sequencing and interlock safety.
