How Does Copper Wire Granulator Work?

The Copper Wire Granulator Work is an advanced recycling system designed to efficiently separate copper from plastic insulation in scrap electrical wires and cables(and sometimes other metals). It is widely used in copper wire recycling plants, cable recycling workshops, and metal recovery facilities.
Core Principle:
The machine utilizes the differences in density and physical properties between copper and plastic, combining crushing, vibration, and airflow separation techniques for separation.99.9% separation rate.

Feeding:
Scrap insulated copper wires of various sizes and types are fed into the machine’s hopper via conveyor belts or manually.
For thicker cables, a separate pre-crusher is often used to pre-crush the material for smoother processing.
Primary Crushing (Granulation):
The wires are fed into a rotating granulator or crushing chamber equipped with hardened steel blades or rotors.
Here, the material is shredded and crushed into uniform small pieces (typically 3-10 mm). This process breaks the bond between the copper core and the insulation without melting or altering the chemical properties of either material.

Separation Stage
Airflow Separation/Vibrating Screen:
The mixture of copper granules and plastic/rubber fragments (now called “granules”) falls onto a vibrating screen or airflow separation system.
Vibrating Screen: The granules are sorted by size. Appropriately sized mixtures continue forward; oversized granules are typically returned to the crusher for secondary crushing.
Airflow Separation (Aspirator): This is the crucial separation step. A controlled stream of air is blown across the falling granules. Due to their lower density, the lighter plastic/rubber fragments are blown away by the airflow into a separate collection bag or bin. The denser copper granules, unaffected by the airflow, fall straight down.

Collection
Copper Output: The separated, pure copper granules are collected in bags or bins. They can now be sold to copper smelters or foundries for smelting and reuse.
Plastic Output: The separated plastic/rubber fragments (often called “fluff”) are collected separately. While of lower value, this material can often be sold for use in the manufacture of plastic lumber, building fillers, or other recycled plastic products.

Structure Of Copper Wire Granulator

Advantages of Copper Wire Granulation Machines

1.Ensuring worker safety: Eliminating the dangers of manual wire stripping (cuts, ergonomic injuries) and the risks associated with burning.
2.High purity, high yield: Achieving copper separation purity of over 99%, maximizing profits.
Integrated structural design, compact structure, small footprint, easy to move, and simple operation with PLC control.
3.As a crucial step in copper wire and plastic separation, gravity separation utilizes Italian air suspension separation technology, allowing for precise adjustment of vibration frequency and material suspension airflow device according to different materials.

4.The crushing system uses SKD-11 alloy blades with a processing hardness of HR58. This ensures high wear resistance and certain toughness of the crushing blades. The structure adopts a staggered shearing design, and the cable grinding equipment casing uses a water cooling system to prevent material overheating and melting after long-term operation.
5.Environmentally friendly and safe: No burning is required, eliminating toxic fumes (e.g., dioxins produced by burning PVC). The entire equipment operates in a fully enclosed system, equipped with an advanced pulse dust removal system to effectively collect dust generated during production and discharge it through the dust removal port.
