Small Copper Wire Granulator for Cable Recycling
The small-scale copper wire recycling machine is a dry-process recycling unit designed to process waste electrical wires, cables, and mixed wire materials. It primarily processes waste wire into copper and plastic pellets through crushing, grinding, and the separation of copper from plastic, making it suitable for small-scale recycling enterprises and start-up recycling plants.
Working Principle of the Copper Wire Recycling Equipment
This small-scale copper wire recycling machine is primarily designed for household waste electrical wires, data cables, telecommunications cables, and other fine-gauge waste wires. Through mechanical crushing and granulation, the equipment separates the copper conductors—which are originally entangled—from the outer plastic insulation.
Upon entering the equipment, the material first passes through a shredding system, which cuts the wires into particles suitable for sorting. Subsequently, the copper-plastic mixture enters an air classification unit, which utilises the differences in density, weight and movement characteristics between copper and plastic to direct the two materials into their respective collection outlets.
Compared to manual wire stripping, mechanised processing reduces repetitive tasks and is particularly suitable for processing waste wires with small diameters, complex structures, or those where manual stripping is inefficient.
Equipment Features and Practical Applications
With a rated processing capacity of approximately 100 kg/h, this compact wire recycling unit is ideal for small-scale recycling and processing projects with limited space and budgets.
Key features include:
Compact design: The equipment has a relatively small footprint, facilitating installation and routine maintenance.
Copper–plastic separation: Through shredding and air classification, the system enables the separate recovery of copper and plastic particles.
Ease of operation: The use of mechanised continuous processing reduces the workload associated with manual sorting and wire stripping.
Resource Reuse: The recovered copper granules can serve as raw material for recycled copper, whilst the plastic components can also be sorted and utilised according to their material type.
It should be noted that actual processing capacity and sorting efficiency are influenced by the wire gauge of the feedstock, the copper-to-plastic ratio, the material of the insulation layer, and the uniformity of the feed. For materials such as fine copper wire and mixed data cables, it is recommended to conduct trial runs in advance to determine the appropriate crushing particle size and sorting parameters.
How to Select a Suitable Small-Scale Copper Wire Granulator?
When purchasing a small-scale copper granulator, one should not focus solely on the rated output; equal attention should be paid to copper recovery rate, sorting purity, energy consumption per unit, and equipment stability.
If the raw materials consist mainly of fine wires, domestic electrical cables and telecommunications cables, particular attention should be paid to the equipment’s ability to recover fine copper wires, to prevent them from being discharged as waste alongside the plastic. At the same time, consideration should be given to the wear resistance of the blades, the ease of replacing the sieve mesh, and the configuration of the dust extraction system.
For users new to the scrap wire recycling industry, this small-scale copper wire granulator serves as an ideal entry-level processing machine. By carefully controlling the feed and sorting parameters, it can transform scrap wire into copper-plastic pellets that are easy to store, transport, and utilise further.
