III. What Do D Series & N Series Copper Granulators Have in Common?

Our D series and N series copper wire shredder machine share the same core purpose: helping you separate copper from plastic efficiently, cleanly, and profitably.

1. Dry Separation Without Water

Both D series and N series cable grinders use dry separation technology. The whole process does not require water, so there is no wastewater treatment, lower environmental pressure, and easier daily maintenance.

Basic parts include a main crusher, air separator, and vibrating table. According to different materials and capacity requirements, you can assemble with a pre-shredder, magnetic separator, or electrostatic separator for better processing performance.

2. High Separation Efficiency

Both series are designed to produce 100% clean copper granules and plastic particles for easier resale. With proper material sorting, correct screen size, stable feeding, and suitable machine adjustment, the copper-plastic separation rate can reach up to 99.9%, so you can recover more valuable copper, reduce material loss, and improve the resale value of final products.

3. Suitable for Various Scrap Wires Below 30mm

Both D series and N series wire choppers can process many types of scrap wires below 30mm, including automotive wiring harnesses, mixed copper wires, square wires, thin wires, household wires, plug wires, net wires and other common waste cables.

4. Flexible Customization

BSGH Granulator can customize voltage, machine layout, and system configuration according to your real requirements. Whether you need to match your local power supply, workshop space, or specific material type, we can adjust the machine solution before production.

5. Easy Operation with Automatic Control

Both series are equipped with an automatic control system to make operation easier and more stable. PLC intelligent control cabinet supports simple start and stop operation, helping reduce manual work and improve production efficiency.

In most standard operations, one worker can feed and monitor the machine, which helps lower labor cost and makes daily cable recycling more convenient.

IV. Key Differences Between D Series & N Series Copper Granulators

Although the basic recycling process is similar, D Series and N Series copper plastic separator are designed for different customer needs. D Series focuses on compact design, easier shipping, and lower investment cost, while N Series is made for higher capacity, heavier-duty operation, and more industrial-scale cable recycling.

1. Blades Material Difference

There are different blade materials for copper granulators, commonly used such as: SKD-11, 96Si, DC53 and so on. BSGH Granulator offers custom blade materials for you, our D Series standard configuration is SKD-11, known for high hardness, strong wear resistance, and good cutting performance. While N Series uses 9CrSi material as the standard configuration, a commonly used steel with good hardness, tempering resistance, and reliable cutting performance.

2. Machine Structure Difference

Workshop space also affects your copper granulator selection. D Series has a more compact structure, fit for customers with limited workshop space. N Series requires a larger layout, suitable for customers who have enough workshop space and large volume capacity.

3. Processing Capacity Difference

You should also consider real processing capacity when investing in a copper granulator. D Series covers a processing capacity from about 70 kg/h to 700 kg/h, ideal for small and medium scrapyards. And N Series offers a higher capacity range from medium about 300 kg/h to 1.5T/h, more suitable for larger cable recycling plants.

4. Price Difference

Of course, price is an essential factor for choosing an optimal machine. D Series is more cost-effective, with prices generally below USD 50,000. While N Series prices usually range from about USD40000 to USD 150000, belong to our higher-end series granulator.
