Extracting copper from cables using a granulator kabel involves several key steps that collectively shred the cables, granulasi bahannya, lalu pisahkan tembaga dari isolasi plastik.

Here’s a detailed breakdown of the process:

Step-by-Step Process of Extracting Copper Using a Cable Granulator

Feeding the Cables

Kabel dan kabel bekas dimasukkan ke dalam mesin.

This can be done manually or through an automated feeding system.

The cables can vary in size and type, termasuk kabel rumah tangga, kabel industri, dan kabel otomotif.

Penghancuran Primer

The cables first pass through a primary shredder, yang memotongnya menjadi lebih kecil, potongan yang lebih mudah diatur.

This initial shredding helps to prepare the material for more precise granulation.

Granulasi

Kabel yang telah diparut kemudian dimasukkan ke dalam granulator, yang selanjutnya mengurangi ukuran bahan menjadi butiran halus.

The granulator uses rotating blades to chop the cables into small particles, usually a few millimeters in size.

This process ensures that the copper and plastic insulation are adequately broken down.

Separation Process

Setelah granulasi, the mixture of copper granules and plastic insulation is processed through various separation systems to isolate the copper:

Pemisahan Udara: An air separator uses airflow to separate lighter plastic particles from heavier copper particles. As the mixed granules fall through a stream of air, the lighter plastic is blown away while the heavier copper falls to a different collection area.

Pemisahan Getaran: Meja atau layar bergetar digunakan untuk memisahkan bahan berdasarkan kepadatan dan ukuran partikel. The vibration helps the heavier copper particles settle, while lighter plastic particles are carried away.

Pemisahan Elektrostatis: Pemisah elektrostatik mengisi partikel dan menggunakan medan listrik untuk memisahkan logam dari non-logam berdasarkan sifat konduktifnya. Tembaga, being a good conductor, is separated from the non-conductive plastic insulation.

Pengumpulan Debu

Throughout the shredding and granulation process, dust collection systems are used to capture and contain any dust generated, ensuring a clean working environment and reducing airborne contaminants.

Collection of Separated Materials

The separated copper granules and plastic fragments are collected in different bins or conveyors.

The copper can be further processed or sold, while the plastic can be recycled or disposed of according to local regulations.

Detailed Workflow Diagram

1. Masukan: Kabel dan kabel bekas dimasukkan ke dalam mesin.

2. Penghancuran Primer: Cables are cut into smaller pieces.

3. Granulasi: Shredded pieces are reduced to fine granules.

4. Pemisahan:

Pemisahan Udara: Lighter plastic is separated from heavier copper.

Pemisahan Getaran: Copper and plastic are separated based on density and size.

Pemisahan Elektrostatis: Copper is separated from plastic based on conductivity.

5. Pengumpulan Debu: Dust is captured and contained.

6. Keluaran: Separated copper granules and plastic fragments are collected.

Key Points in the Extraction Process

Efisiensi: The combination of shredding, granulation, and multiple separation techniques ensures efficient recovery of high-purity copper.

Otomatisasi: Modern cable granulators are automated, reducing the need for manual labor and increasing processing speed.

Kemurnian: Advanced separation methods result in high-purity copper granules, yang dapat langsung digunakan kembali di berbagai industri.

Benefits of Using a Cable Granulator for Copper Extraction

Economic Advantage: Recovered copper can be sold, providing a significant revenue stream.

Dampak Lingkungan: Recycling copper reduces electronic waste and the need for new copper extraction, melestarikan sumber daya alam.

Efisiensi Operasional: Automated and efficient processing increases productivity and reduces labor costs.

Keamanan: Built-in safety features and dust collection systems ensure a safer working environment.

Dengan mengikuti langkah-langkah ini, a cable granulator efficiently extracts copper from scrap cables, providing both economic and environmental benefits while promoting sustainable recycling practices.
