Advanced Copper Scrap Processing Systems: From Shredding to Purification

1. Material Overview

Copper Scrap Characteristics

Infinite recyclability: Retains 100% conductivity through cycles

Common forms: Electrical wires (45%), plumbing tubes (30%), industrial scrap (25%)

Contamination types: PVC insulation (up to 40% by weight), steel fittings

Processing Challenges

Density variations: 2.5-8.9 g/cm³ depending on alloy composition

Thermal sensitivity: Requires low-RPM shredding to prevent oxidation

Safety requirements: Spark-resistant construction for copper powder

2. Technical Solution

Three-Stage Processing Flow

Pre-shredding: Coarse reduction to<150mm fragments

Liberation: Separation of copper from insulation materials

Final sizing: Homogenization to<20mm granules

Key Performance Metrics

Throughput range: 5-20 tons/hour

Energy efficiency: 0.8-1.2 kWh/kg processed

Dust emission:<5mg/m³ with integrated filtration

3. Equipment Specification
