What is your product?
A range of Copper granulators capable of processing car looms.
How does it work?
The machine has three major components. A pre shredder to chop the cable into approximately 50mm long strands. At the same time, it adds powder to the cable to neutralise the sticky glue from the tape used to bind the loom. The chopped cable is transported by a conveyor up into the cable granulator where the mill and then turbo device, separate the copper from the plastic. The final step is the vibrating table which is able to provide two clean outputs, one for copper the other for plastic.
Where would it ideally be used?
End of Life Vehicle processors.
How is it different?
Handling car loom has always been a problem for granulators as the sticky tape tends to ball up in the machine. The addition of the powder and additional cooling overcomes this issue.
Many competitors struggle to process even standard scrap cable without melting the plastic in the mill, so adding the sticky tape gives them a real problem operating the machines on a continuous basis. The Stokkermill naturally runs at a much lower temperature, ensuring that it don’t exceed the melting point of the plastic and tape.
What benefits does it offer?
Car loom is typically sold for around £1,600/tonne, but the copper content is worth circa £2,800/tonne. This technology allows the recycler to benefit from the true value of the copper.
Where has it been used?
A number of these systems are operating in the UK and the USA. In the UK, three systems have already been sold into the market with the first running in the Manchester area.
Cost depends on the size of machine but the returns on investment are amazing. The typical payback period is under six months.
What about maintenance?
Maintenance is minimal. The blade settings in the machine need to be checked on a weekly basis, which is a 10 minute job. Blades typically need re-sharpening every 200 hours of operation. Other than that, there is little to do.
Any future applications?
The Car loom range will handle both looms and standard cable, so if you don’t have enough volume of car looms to justify the purchase then you can always bulk out with granulating standard scrap cables.
