Choosing the right cable recycling equipment is one of the most important decisions an industrial recycling business will make. The line you install determines how much copper and aluminum you actually recover, how clean that metal is when it reaches the buyer, and whether your operation can keep pace with the scrap coming through the gate. Buy on price alone and you may end up with a system that cannot handle your cable mix. Buy on brochure capacity and you may discover the real output is far below what the sales sheet promised.
The good news is that the selection process is not complicated once you understand the factors that matter: the type of cable you process, the separation technology behind each machine, the capacity you genuinely need, and the support the manufacturer provides after the sale. This guide walks through each of those points so you can compare options with confidence.
Start with your material, not the machine
The most common mistake in equipment selection is starting with price or motor power. Two machines with identical power ratings can perform very differently, because performance depends on what you feed them. Clean, large-diameter single-core cable can be handled by a simple stripping machine, while mixed appliance harnesses, automotive wiring and fine communication cables usually need granulation and separation.
Before you compare quotations, build a simple table of the material you plan to process. Note the cable sources (appliance, automotive, telecom, construction), the approximate copper content, the diameter range, the insulation type, and how much contamination such as steel connectors, plugs or stones is mixed in. This one page of notes becomes the foundation for every other decision. If most of your scrap is large and clean, a scrap cable stripper equipment may be all you need. If you process mixed, fine or heavily contaminated wire, you will need a granulation line with proper separation and dust control.
Understand the main types of cable recycling equipment
Cable recycling equipment falls into a few broad categories, and most industrial operations use more than one of them in sequence:
Scrap cable strippers. These strip the insulation from cable and are best suited to large-diameter, relatively clean wire. They come in manual, semi-automatic and automatic versions, and portable models are available for small operations. Stripping is economical when the cable is big enough that labour cost per kilogram stays low, but it is not practical for fine or heavily tangled wire.
Cable granulators. A granulator crushes the cable into small particles and then separates the metal from the plastic using airflow, vibration and screening. This is the workhorse for mixed and fine wire. Dry-type granulators, which need no water, are the most widely used for medium and large operations because they have low running costs and no wastewater to treat. Compact models are available for smaller volumes, while larger units such as the WCD-1200S handle high daily throughput.
Complete cable recycling plants. For high-volume operations, a full plant integrates pre-shredding, granulation, separation and dust collection into one line. This is the most efficient option when you process truckloads of mixed cable every day, because it minimizes manual handling and keeps output consistent.
Pre-shredders. Bulky cable bundles, long harnesses and connector-heavy scrap can bridge inside a small granulator. A heavy pre-cutting stage reduces the material to a manageable length and makes feeding stable. If your site also processes other light metal scrap, a multi-purpose shredder can serve both duties.
Key specifications to evaluate
Once you know which type of machine fits your material, compare the following specifications across suppliers:
Throughput capacity. Capacity is usually quoted in kilograms per hour or tons per day, but the number only means something if you know the feed condition behind it. A rating based on clean copper wire will not hold when you feed mixed appliance wire or cable with heavy connectors. Ask the supplier what feed the rating assumes, and size the machine for your realistic input.
Separation efficiency and copper purity. Purity and recovery are related but not the same. A machine can produce very clean copper while losing too much metal to the plastic outlet, or it can recover more copper while carrying more plastic contamination. Decide what copper purity your buyer will accept, and ask the supplier what recovery rate the line can maintain under your feed conditions.
Input diameter range. Make sure the machine can handle the thickest cable you expect to process. Some granulators only accept wire under a certain diameter, which forces you to pre-cut larger cable or add a stripping step.
Power requirements. Most industrial units need three-phase power at 380V. Confirm the supply available at your site before you commit, and factor in the total connected load of the whole line, not just the main motor.
Dust collection. Cutting PVC and rubber insulation creates fine dust at the crusher, the conveyor and the separator. A closed structure with negative-pressure dust collection keeps the workspace clean, protects operators, and is often required for environmental compliance. Dust control is not an accessory to skip.
Maintenance access. Blades, screens and bearings are the parts that wear out. Easy access to these components means less downtime when you need to change a screen or inspect a knife. Ask how long a screen change takes and whether spare parts are stocked locally or shipped from the factory.
A step-by-step selection process
Follow this sequence to turn your requirements into a shortlist:
1. Assess your volume. Track your cable scrap over a few weeks. If you consistently process more than a few hundred kilograms per week, automation quickly becomes worthwhile; below that level, manual stripping may be more economical.
2. Define your cable mix. Use the material table you built earlier. Separate the scrap into streams that can be stripped and streams that must be granulated, and note which fraction dominates.
3. Set a realistic budget. Include equipment, installation, dust control, tooling and training in the figure. The cheapest quotation can become the most expensive if the line cannot process your real cable mix.
4. Verify space and utilities. Measure the available floor area, confirm three-phase power, and check installation height, forklift access and where the dust collector will sit. A compact line is still hard to run if operators cannot open access doors or reach the discharge area.
5. Request performance data. Ask for test videos, separation efficiency reports and customer references. If possible, arrange a trial with your own material or a comparable mix. A short demonstration with clean cable does not prove performance on automotive harnesses or appliance-wire scrap.
6. Evaluate after-sales support. Compare warranties, spare parts availability, installation guidance and operator training. For an overseas purchase, confirm how commissioning is handled and how quickly technical support responds.
Questions to ask a supplier before buying
Sending a short technical questionnaire before you ask for a final price helps the supplier size the line correctly and gives you a fair basis for comparing offers:
What cable types, diameter ranges and contamination levels will the line process? What capacity, in kilograms per hour, is needed under real feed conditions? What copper purity and plastic cleanliness does your buyer require? What power supply, floor area and installation height are available? How many operators will sort, feed and maintain the line? And what spare knives, screens and filters are included with the first order?
A supplier that answers these questions with concrete numbers, rather than vague assurances, is usually one you can work with. A supplier that avoids the questions or pressures you for a quick decision is a warning sign.
Common mistakes to avoid
Buying only by motor power. Motor power matters, but separator design, screen area, airflow control and dust collection often decide whether the plant can produce clean copper consistently.
Ignoring pre-sorting. Steel connectors, stones and batteries are not cable. If they enter the granulator they can damage the knives, contaminate the output and slow the whole line. Build a simple pre-sort step into your workflow.
Testing only clean material. Always test with material that looks like your real feed. A demo with clean single-core cable tells you nothing about performance on mixed appliance wire.
Skipping dust planning. Cable recycling creates dust at every stage. Make sure the dust-control capacity matches the line and the room, not just the brochure.
No acceptance standard. Define the copper purity, copper loss, hourly throughput and operating conditions you expect before installation, so commissioning has a clear target and both sides know what success looks like.
Choosing a supplier you can grow with
The equipment is only half of the purchase. A manufacturer that understands the full recycling process, can help you plan the plant layout, and stays available after commissioning is worth more than a slightly cheaper machine from a supplier you cannot reach. Look for a company that manufactures its own line rather than reselling, that can customize the configuration to your material, and that has a track record of installations in your region.
San Lan Technologies, for example, has manufactured cable recycling machines and complete cable recycling plants since 2007, and supplies customers in more than twenty countries. Its cable line includes compact granulators with dry separators for small and medium volumes, high-capacity granulators for continuous production, scrap cable strippers for large-diameter wire, and pre-shredders that prepare bulky scrap for the granulator. Because the company also builds battery, circuit board and refrigerator recycling plants, it can plan a whole e-waste facility rather than a single machine.
Whichever supplier you choose, the principle is the same: match the machine to your material, verify the numbers with a real test, and confirm the support before you sign. Do that, and your cable recycling equipment will pay for itself through cleaner metal, higher recovery and less downtime.
