Here’s a detailed breakdown of the process:

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

Feeding the Cables

Scrap cables and wires are fed into the machine.

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

The cables can vary in size and type, including household wires, industrial cables, and automotive wiring.

Primary Shredding

The cables first pass through a primary shredder, which cuts them into smaller, more manageable pieces.

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

Granulation

The shredded cables are then fed into a granulator, which further reduces the size of the material into fine granules.

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

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

Air Separation: 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.

Vibration Separation: A vibrating table or screen is used to separate materials based on density and particle size. The vibration helps the heavier copper particles settle, while lighter plastic particles are carried away.

Electrostatic Separation: An electrostatic separator charges the particles and uses an electric field to separate metals from non-metals based on their conductive properties. કોપર, being a good conductor, is separated from the non-conductive plastic insulation.

Dust Collection

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.
