Metal separation

Achieving maximum clean metal recovery

As a raw material, metal can be repeatedly returned to the resource cycle with very little loss, but the success – and value – of the process greatly depends on the cleanliness of the materials recovered. With the commodity rate of metals constantly fluctuating, the quality yield from a recycling line therefore needs to be as high as possible.

  • Why shred to boost the metal separation process?

    Shredders can achieve a far more sophisticated metal processing method, when compared to traditional shears. This helps liberate the high value materials that would otherwise be difficult to extract, especially when ‘locked’ in complex composite products such as WEEE or uPVC windows.

  • Why shred to boost the metal separation process?

    Shredding helps relieve metals of other contaminants such as plastic film that would otherwise render the recyclate virtually worthless.

  • Why shred to boost the metal separation process?

    Once ‘freed’, downstream segregation and separation equipment is better equipped to do its job, which results in more tonnage from the line and, of course, greater revenue.

  • Why UNTHA?

    Metal shredding is an intensive process that puts the technology through its paces. Machinery therefore needs to have a sturdy frame, with hard-wearing parts and foreign object protection, to ensure equipment that is built to last. This describes our shredders perfectly.

  • Why UNTHA?

    Particle homogeneity – a precise shred – boosts the recycling and remanufacture potential of the metals, so we’ve thought carefully about configurable cutting systems and screens that regulate fraction sizing.
