An eddy current separator (ECS) is a key recycling machine used to separate valuable non-ferrous metals such as copper and aluminum from mixed waste streams.
Traditional ECS systems work well for non-ferrous recovery but cannot effectively process ferrous metals like iron and steel. Ruijie’s customized eddy current separator solves this challenge by combining magnetic separation and non-ferrous sorting into one integrated system for higher purity and greater efficiency.
What Is an Eddy Current Separator?
An eddy current separator is an industrial sorting machine designed to recover conductive non-ferrous metals from mixed materials.
It is commonly used to separate:
- Copper
- Aluminum
- Brass
- Zinc
from non-conductive materials such as:
- Plastic
- Glass
- Rubber
- Wood
ECS systems are widely used in recycling plants because they improve metal recovery rates and increase the value of recyclable materials.
How Does an Eddy Current Separator Work?
An eddy current separator uses electromagnetic induction to separate conductive metals from non-conductive waste.
A high-speed magnetic rotor creates a rapidly changing magnetic field. When non-ferrous metals pass through the field, eddy currents are generated inside the metal particles.
These currents create an opposing magnetic force that repels the metals away from the conveyor trajectory.
As a result:
- Non-ferrous metals are ejected forward
- Non-metallic materials fall naturally
- Adjustable splitters separate the materials into different discharge ports
This allows continuous and efficient sorting of mixed waste streams.
The Limitation of Standard Eddy Current Separators
Traditional ECS machines cannot effectively process ferrous metals such as iron and steel.
When magnetic materials remain in the waste stream, they can:
- Reduce sorting accuracy
- Damage conveyor belts
- Lower copper and aluminum purity
- Increase maintenance costs
- Require additional separation equipment
For recycling plants processing mixed metal waste, this creates unnecessary operational complexity.
Rui Jie Customized ECS Solution
To solve this issue, Rui Jie developed a customized eddy current separator with integrated magnetic separation technology.
The system combines ferrous metal removal and non-ferrous metal recovery into one compact solution, improving efficiency while reducing equipment footprint and operating costs.
It is ideal for:
- E-waste recycling
- Auto shredder residue (ASR)
- Municipal solid waste (MSW)
- Construction waste recycling
- Industrial slag processing
- Mixed scrap metal recovery
How the Integrated Separation System Works
1. Material Feeding
Mixed materials containing iron, steel, copper, aluminum, and non-metallic waste are evenly fed onto the conveyor belt.
2. Ferrous Metal Separation
The integrated magnetic separator removes ferrous metals such as iron and steel from the material stream.
3. Non-Ferrous Metal Recovery
The remaining materials pass through the ECS rotor, where copper and aluminum are repelled into a dedicated discharge area.
4. Non-Metal Discharge
Plastic, glass, rubber, and other non-conductive materials fall into the residual waste outlet.
This process enables one-step separation of ferrous metals, non-ferrous metals, and non-metallic materials.
Advantages of Rui Jie Eddy Current Separators
High Purity Recovery
The system achieves non-ferrous metal purity levels of up to 98% or higher.
Reduced Equipment Costs
Integrated magnetic separation eliminates the need for separate processing equipment.
Stable Continuous Operation
High-grade NdFeB magnetic components support reliable 24/7 industrial operation.
Low Maintenance Requirements
Durable construction and efficient design help reduce downtime and maintenance costs.
Flexible Customization
Rui Jie provides customized solutions based on material type, processing capacity, and plant requirements.
Copper-Aluminum Separation with X-Ray Sorting
For higher purity requirements, Rui Jie systems can be combined with X-ray sorting technology to separate copper and aluminum individually.
X-ray sorting uses density differences to identify metals with high precision.
For example:
- Copper density: 8.96 g/cm³
- Aluminum density: 2.7 g/cm³
This allows accurate separation of mixed non-ferrous metals.
Benefits of X-Ray Metal Sorting
Ultra-High Purity
Copper and aluminum separation purity can reach up to 99.9%.
High Throughput
The system supports high-speed processing for large recycling lines.
Multi-Metal Separation
X-ray sorters can also separate:
- Zinc
- Lead
- Stainless steel
- Heavy non-ferrous metals

ECS systems can separate copper, aluminum, brass, zinc, and other conductive non-ferrous metals.
What is the purity of Rui Jie ECS systems?
Rui Jie customized systems can achieve non-ferrous metal purity levels above 98%.
What industries use eddy current separators?
They are widely used in recycling plants, e-waste processing facilities, municipal waste treatment centers, and scrap metal recovery systems.
What is the difference between ECS and X-ray sorting?
Eddy current separators separate conductive and non-conductive materials, while X-ray sorting separates metals based on density differences.
