FAQ: TOP 10 Useful Frequently Asked Questions About Copper Granulators

Copper wire granulators have become essential equipment for recycling companies, industries and individuals that deal with scrap copper wires and cables. These machines effectively recycle waste copper wire and cabels, help you save time and ensure maximum profits. If you’re considering investing in a copper wire granulator, you might have some doubts. Here, BSGH provides you with top 10 frequently asked questions and answers about copper wire granulators, the author has over 15 years of export and customer service experience, ensuring clear and insightful information:

1. What mechanism did the wire granulator use for separation?

Many people are curious about how BSGH Granulator works for separation. When using a copper wire granulator, first you need to crush the wire into a mixture. Afterward, we use the following 4 methods for separation: air separation, vibration, magnetic selection and electrostatic separation.
First, airflow separation system to segregate the shredded mixture. Copper and plastic granules are separated by air separation system according to their weight after the plastic and copper will collect in different outlets.
Then, small table vibrator is used for dual separation. Small table vibrations drain small and heavier copper particles to the next layer, whereas the bigger and lighter plastic particles are transported in the upper layer.
When wires have magnetic materials like steel and iron, a magnetic separation system is needed, This system is added above the copper outlet or frame above the conveyor belt to remove materials like iron in your wires. Magnetic particles are attracted to the magnetic surface, while non-magnetic particles remain unaffected and continue along their path.
To recycle more completely, you need to assemble the electrostatic separator for thin wires. Electrostatic separators are based on the principle of electrostatic attraction or repulsion to separate materials with varying of electrical conductivity.

2. Can the machine process various types of scrap wires and cables?

Classified by diameter: Actually no, armored cables and wires with a diameter greater than 30mm are not recommended for processing, but several pcs are no problem, It’s important to note that cable granulator machines are not well-suited for armored cables or cables with larger diameters. We recommend processing wires diameters within 20mm to 30mm as a general guideline, for wires exceeding this diameter in large amounts, recommend to recycle by wire stripper machine.
Classified by cable types: Copper wire granulators are proficient in processing wires with diverse insulation materials like plastic, rubber, and PVC; and processing thin cables such as household wires, communication cables and industrial cables, especially mixed cable, complex cable and slim cable. They are suitable for wires that challenge for wire stripper machines, such as car wires, plug wires and telephone wires.

3. Can the granulator be adjusted to accommodate different output sizes?

Absolutely, you can adjust the size of copper rice through the types of mesh screen and the changes of processing parameters. BSGH granulator equipped with different crusher screens size, covering diameters of 3mm, 4mm, 5mm and 6mm or bigger, achieve the desired granularity for your copper granulation process, catering to diverse applications and requirements.

4. What is the daily operational duration of the machine?

How long can the machine operate within a single day? This is a question that most people are curious about. Normally, the machine can work continuously as desired, however, to ensure a longer lifespan, we recommend about every 4 hours have a rest, workers also need to rest. For instance, if you activate the machine in the morning, power it off during lunch to allow for cooling and rest, then restart it in the afternoon, you can operate like this in one day. By following this, the machine will not only reduce maintenance costs but also have optimal performance.

5. How many people are needed to operate the machine？

For small quantities of recycling using small or medium-sized machines like BS-D75, BS-D20, BS-D30 and BS-D60, one person is enough. However, for larger capacity machines like BS-N130, ECO1000, BS-F1000 and BS-F3000, it’s better to have 2 workers to ensure optimal recycling results, also, they just need to put the scrap wires on the conveyor belt and take away end products at regular intervals.
All our machines are designed with automatic operation. Normally, the worker just needs to learn how to operate the machine, the operation is simple and available for anyone.

6. When should I change the blades?

The process of scrap wire crushing plays a crucial role in the copper wire granulator machine. Scrap wires must be shredded into a mixture by sharp blades before separation. It’s important to note that these blades have a limited lifespan due to continuous use. So how long should I change the blades? Several factors determine the longevity of the blades: the frequency of machine use and the types of raw materials processed significantly affect the blades’ lifespan.
1: When the blades become dull, they can be sharpened.
2: When there are crushed long wires, you can change or sharp blades.
3: When the separation effect is not good, you can change or sharpen blades.
4：When the knife edge can’t be sharpened, change it.

7. Why is the machine priced so differently?

Because different machines have varying capacities, diverse technologies and incorporate various raw materials, etc., for different capacities, machine prices are not the same, the bigger the more expensive. 

All bsgh granulators can be categorized into three types: large, medium, and small based on their capacity, all these machines adopt mature and most advanced technology, the best steel raw materials, in order to reach the best effect.

8. How to choose a suitable copper wire granulator separator?

The more you understand your needs, the better you make your machine purchase decision.
Start by identifying the type of scrap copper wire you have， our copper wire granulator works well for small, thin, and mixed wires; enameled, rubber-insulated and PVC-insulated copper wires perfectly.
Next, consider your daily processing amount.
Different machines have different processing capacities. For instance, our BS-F3000 handles 1200~1500kg/h, BS-N130 does 400~700kg/h, BS-N125 manages 300~500kg/h, and BS-D70 handles 70kg/h, predict your processing needs based on current and future growth to choose the suitable one for you.

9. What is the warranty for machines?

BSGH granulators have 12 month warranty period. Within a one-year span, if any of the main components are damaged not caused by human intervention, we can replace it for free.
We also offer round-the-clock online assistance, Our professional team is available 24 hours a day to promptly and expertly solve any issues you may encounter.

10. How to install granulators?

For small machines, it comes in an integrated type, you only need to connect to the power source, it’s ok. Regarding the larger model, some of the high parts will be disassembled for transportation, We will mark them clearly to guide you in reassembly.
For the large granulators, we have more than 10 technicians who fly all over the world to offer overseas installation services to our customers, please note that customers are responsible for covering all technician-related expenses:
1: Pay all costs of technicians: besides visa fee, hotel and round trip air ticket and meal fee;
