In Germany alone, there are currently about 150,000 tonnes of cable waste every year. Worn out electric appliances, telecommunications, mining, overhead transmission lines – cable harnesses are all around us. And below the ground, there are millions of kilometres more of cable which will need to be replaced at some point. Cable recycling, therefore, is an area of expertise that is in high demand. And since cable contains metals such as copper, aluminium, lead, and steel they are extremely high in recyclable fractions.
Recovering these recyclable fraction from cable demands a high degree of expertise as well as the right machine technology. The German plant manufacturer MeWa now offers for this application a range of pre-shredders with shredder geometry especially designed for breaking down cables. With a throughput capacity of up to three tonnes per hour, this latest development works very efficiently and with great precision. This robust machine can significantly increase the throughput capacity of a cable recycling plant. Compared to previous solutions with pre-, after- and fine shredding, a complete work step can be eliminated.
The machine works according to the guillotine shear's functioning principle and is equipped with changeable triangular blades. A spur gear unit in the machine is powered by a electric motor. The machine is manufactured in a solid steel-welding construction for completely vibration-free operation. The granulator’s screens are easy to change and achieve a grain size of a 20 to 50 mm diameter. If required, special sizes are available. The feed chute is 2.30 meters wide thus equipped for grab loading.
The machine is specifically adapted to the further processing with granulators. MeWa offers ready-to-use recycling equipment, from one expert source. Specifically designed separation technology finally delivers separated metal and insulation materials. This especially applies to the copper; its final quality can be compared to that of primary raw materials.
