Cable materials were often lost in the treatment and sorting processes available till now, which meant a financial loss due to the high proportion of copper they contain. New sorting technologies such as the TITECH finder are now capable of detecting these cables.
Recover up to 98% of wires from metal scrap!
Copper cables and free copper particles are valuable components which are contained in lots of waste fractions such as:
- Heavy fractions from automobile shredders (SSF)
- Light fractions from automobile shredders (SLF)
- Waste electrical and electronic equipment (WEEE)
- Residual materials and metals from dense medium separation systems (DMS)
The safe identification of copper cable in these material flows with conventional sorting technology is not possible. Cable processors and secondary copper smelters demand high purity mono-fractions of copper concentrate and cables. These can only be efficiently gained by using the new sensor-supported sorting systems.
Wire recovery system
TITECH has developed a wire recovery system which unifies two technologies:
Stage 1 – Recover up to 98% of insulated and bare wires
The TITECH finder [poly] not only recognises fine metal particles with a highly-sensitive electromagnetic sensor (EM) but can also identify insulating polymer coatings made of PVC, PP, PE or rubber with an additional high resolution near infrared sensor (NIR).
Stage 2 – Recover up to 95% of insulated wires
The signals from both sensors are analysed with the help of the newly developed SUPPIXX image processing technology which delivers high-precision results. This means that the insulated copper cables can be safely identified and separated with up to 90% of purity.
Our wire recovery sorting systems can be seamlessly integrated into your own system and adapted to suit the material and particle size. The following flowchart shows the stage at which TITECH sorting system can be optimally deployed.
The input material, which has been crushed and separated from light parts, is then filtered using defined particle sizes. Magnets and eddy current separators separate the ferrous or non-ferrous metals.
The TITECH finder then separates the remaining metals including insulated copper cables. The TITECH finder [poly] gains a high purity mono-cable fraction from this metal concentrate. No metal particles are lost thanks to the two-stage sorting which results in the maximum recovery of cables and copper particles.
