Efficient Copper Wire Granulator for Pure Metal Recovery

The Imperative of Copper Recycling and Granulation Technology

The escalating demand for raw materials and increasing environmental concerns have placed a significant emphasis on sustainable resource management. Copper, a vital metal in numerous industries, is a prime candidate for efficient recycling. The global copper recycling market is projected to grow significantly, driven by regulatory pressures, rising primary copper costs, and the economic benefits of recovering secondary raw materials. Technologies that facilitate this recovery are critical. One such innovation, central to modern scrap copper processing, is the Copper wire granulator. This advanced machinery plays a pivotal role in transforming scrap copper cables and wires into high-purity copper granules and plastic insulation, ready for re-entry into the manufacturing cycle. Its efficacy directly impacts cost savings, energy consumption, and environmental footprint across various industrial sectors.

Industry trends indicate a continuous push towards higher purity output, greater automation, and improved energy efficiency in recycling equipment. Granulation technology is evolving to handle a wider variety of cable types, including fine wires and armored cables, with minimal material loss and maximum separation rates. This evolution underscores the importance of investing in robust, reliable, and technologically advanced granulation systems to meet current and future recycling demands.

Detailed Process Flow of a Modern Copper Wire Granulator System

The operation of a high-performance Copper wire granulator system involves a meticulously engineered multi-stage process designed to achieve optimal separation efficiency and material purity. The entire system is built with longevity and performance in mind, utilizing advanced manufacturing techniques and materials.

Core Manufacturing Processes and Materials:

• Structural Components: Chassis and main frames are typically constructed from robust carbon steel, often Q235 or Q345, precisely cut using CNC plasma or laser cutting, followed by precision welding to ensure structural integrity and vibration damping.
• Granulator Blades: Critical for effective shredding, these blades are forged from high-alloy tool steels such as D2 (Cr12MoV) or SKD-11, known for their exceptional hardness, wear resistance, and toughness. Heat treatment processes, including vacuum quenching and tempering, achieve Rockwell hardness ratings of HRC 58-62, significantly extending service life. CNC machining ensures precise geometries for optimal cutting performance and easy replacement.
• Screens: Perforated screens within the granulator are made from hardened alloy steel, designed for abrasion resistance and consistent particle sizing.
• Separation Components: Air separation tables and vibratory separators incorporate high-grade stainless steel (e.g., SUS304) for contact surfaces to prevent corrosion and ensure hygienic processing, critical for maintaining copper purity.
• Quality Assurance: All major components undergo stringent quality control, adhering to ISO 9001 standards. Material certifications and non-destructive testing (NDT) are performed on critical welds. Operational noise levels comply with ANSI S12.60 and CE directives.

Operational Steps:

1. Feeding and Pre-shredding: Scrap copper wires, often in bundles or coils, are fed into the system. Depending on the material size, an optional pre-shredder may reduce larger cables into manageable lengths (typically 20-50mm) to optimize granulator throughput and prevent jamming. This stage is crucial for initial size reduction and ensuring consistent feed.
2. Granulation: The pre-shredded material or direct feed enters the primary granulator. Here, rotary and stationary blades precisely cut and pulverize the wires and insulation into small, uniform particles (typically 1-5mm). The granulator's design minimizes heat generation, preserving material integrity and preventing copper oxidation.
3. Air Separation (Pneumatic Separation): The mixed granules are then conveyed to an air separator. Utilizing principles of aerodynamics and material density, lighter plastic insulation is separated from the heavier copper granules through an upward airflow. This process significantly increases the purity of the copper.
4. Vibratory Separation: For even higher purity, the output from the air separator often passes over a vibratory separation table. This stage uses a combination of vibration, airflow, and specific gravity to further refine the separation, ensuring copper purity typically exceeding 99.5%.
5. Dust Collection: Throughout the process, an integrated dust collection system captures fine particles and airborne contaminants, maintaining a clean operating environment and complying with environmental regulations. This also recovers any fine copper dust that might otherwise be lost.
6. Output: The system yields clean copper granules, typically 1-5mm in size, and separated plastic insulation, both ready for reuse.
