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.
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.
Shredding helps relieve metals of other contaminants such as plastic film that would otherwise render the recyclate virtually worthless.
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.
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.
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.
We’ve developed a unique metal clean up system that has attracted the attention of operators worldwide, due to the 80% improvement in high quality recyclate recovery rates it can achieve. This can equate to thousands of pounds of additional revenue per month.
UNTHA can supply standalone shredding technology or end-to-end turnkey metal separation solutions complete with shredder, conveyors, magnets, separators and more.
