Product Introduction

An Eddy Current Separator (ECS)​ is an advanced sorting machine that utilizes the principle of electromagnetic induction to efficiently separate non-ferrous metals​ (such as copper, aluminum, zinc, and brass) from mixed waste streams. It is a core equipment in modern recycling and resource recovery industries.

1. Working Principle

The ECS features a high-speed rotating magnetic rotor (typically constructed from high-performance rare-earth magnets). As conductive metals pass over this rotor, the rapidly alternating magnetic field induces eddy currents​ within the particles. These eddy currents generate their own magnetic field, which repels the metal particles, "jumping" them away from the non-conductive materials (like plastic, glass, and wood). This physical separation allows for the precise recovery of valuable metals.

2. Key Advantages & Features

• High Efficiency & Purity:​ Achieves separation efficiency of over 95% for metals like copper and aluminum, significantly improving product purity and metal yield.

• Non-Contact & Dry Process:​ Operates without water or chemicals, making it an environmentally friendly solution that reduces operating costs.

• Adjustable Repulsion Force:​ The magnetic rotor speed and frequency are adjustable via VFD (Variable Frequency Drive), allowing optimization for different metal sizes and types (e.g., fine granules vs. large fragments).

• Robust & Low Maintenance:​ Simple mechanical structure with a durable non-metallic shell ensures reliable operation and minimal downtime.

• Selective Separation:​ Effectively distinguishes conductive non-ferrous metals from non-conductive materials and inert substances.

3. Application Scope

ECS machines are widely used in the following fields:

• E-Waste Recycling:​ Recovering copper, aluminum, and precious metals from shredded electronic waste (PCBs, cables).

• Automotive Shredder Residue (ASR):​ Separating aluminum alloys and copper from car shredder light fractions.

• Municipal Solid Waste (MSW):​ Extracting aluminum cans and non-ferrous metals from household or industrial waste.

• Plastics & Glass Recycling:​ Purifying plastic flakes or crushed glass by removing metal contaminants (e.g., aluminum caps, copper wires).

• Metal Scrap Processing:​ Sorting mixed non-ferrous metal fragments in scrap yards and foundry sand
