Why Cable Recycling Needs a Shredder

Power cables are everywhere — in buildings, vehicles, and industrial systems. When they reach end-of-life, they become a significant e-waste stream. Landfilling cables wastes space and risks leaching toxins from plastic insulation and metal conductors. Recycling recovers valuable copper and aluminum while keeping hazardous materials out of the environment. A cable shredder is the critical first step in this process.

What Cables Are Made Of

A typical power cable contains three main layers:

Conductor — Copper or aluminum, making up 60–70% of cable weight

Insulation — PVC, PE, PP, or XLPE surrounding each conductor

Outer jacket — PP cord, rubber, or armored steel for protection and shaping

Both metal and plastic are highly recyclable. Copper and aluminum can be recovered indefinitely without quality loss, making cable recycling one of the most profitable segments in e-waste processing.

The Cable Recycling Process

1.Shredding — A cable shredder cuts cables into small pieces, liberating metal from insulation

2.Separation — Air classification, vibration, or electrostatic methods split copper/aluminum from plastic

3.Granulation — Fine grinding produces clean copper granules and plastic chips

4.Recovery — Metal is melted and cast into ingots; plastic is pelletized for reuse

Wanrooe Cable Shredder Solutions

Single shaft shredder — Delivers uniform output size with screen control. Ideal when you need consistent chip dimensions for downstream separation equipment. Best for clean cable streams where metal recovery purity is the priority.

Double shaft shredder — Handles mixed, bulky, or armored cables with high torque. The tearing action processes thick jackets and steel reinforcement without jamming. Output is less uniform but throughput is higher.

Selection depends on cable type, diameter range, capacity target, and required output size. Contact us with your material sample and specifications — our engineering team will recommend the most cost-effective configuration.

FAQ: Cable Shredding

Can I shred cables with the insulation still on?

Yes. Shredding is designed to handle intact cables. The blades cut through plastic, rubber, and metal together. Separation happens after shredding through air tables, vibrating screens, or electrostatic separators.

What about armored or steel-reinforced cables?

Double shaft shredders handle these with hardened blades and high torque. Magnetic separation after shredding removes ferrous armor. For very thick armored cables, a four shaft shredder may be necessary.

How clean is the copper after shredding and separation?

A well-configured line achieves 99%+ copper purity with minimal plastic contamination. Purity depends on shredder output uniformity and the efficiency of your separation stage. Granulators produce cleaner output than shredders alone.
