涡流分选机是我们在回收行业中经常推荐给客户的非铁金属分离设备之一。它也被称为涡流分选机、铜铝分离器或非铁金属铝涡流分选器。该设备主要用于自动分离铜、铝等非磁性金属与混合材料，适用于旨在降低人工成本和实现稳定长期运行的回收厂。
在与客户的沟通中，我们发现大多数关注点集中在三个关键点：可以处理哪些材料，分离的清洁度，以及机器是否可靠用于连续运行。以下从这些实际角度介绍涡流分选机。
我们如何解释涡流分选机的工作原理
涡流分选机的工作原理基于纯物理分离原理，利用材料在磁场中的不同物理性质。在操作过程中不需要化学品，也不会产生废气或废水，这对于具有环境合规要求的客户尤为重要。
当混合材料通过高速旋转的磁辊时，铜、铝等非磁性金属在交变磁场下产生涡流。因此，这些金属的轨迹与非金属材料不同，从而实现自动分离。
该机器配备了四个不同材料类型的排放口，包括塑料排放口、铁金属排放口，以及用于非铁金属如铝和铜的单独排放口，实现多材料的分类回收。
通过控制磁辊的正转或反转，机器可以适应不同尺寸的材料。它对粒径为2毫米及以上的材料提供稳定的分离性能。

What Materials Are Suitable for an Eddy Current Separator Machine?
In real projects, our eddy current sorting machines are commonly used for sorting the following materials:
- Shredded municipal solid waste
- Industrial waste and scrap
- Electronic waste and circuit boards
- Glass fragments
- Waste plastic doors and windows
- Municipal wood waste
- Boiler bottom ash
- Mixed metal materials
- Shredded scrap automobiles containing copper, aluminum, and other non-ferrous metals
If your material stream contains both non-metals and non-magnetic metals such as copper and aluminum, the eddy current separator is usually recommended as a key downstream sorting machine, working together with crushers and conveying systems.
Why More Customers Are Replacing Manual Sorting
In earlier stages, many recycling plants relied on manual sorting for copper and aluminum separation. However, as processing volumes increase, limitations in efficiency and consistency become more apparent.
Based on customer feedback, eddy current sorters offer several clear advantages over manual sorting:
- Stable and high sorting speed
- High separation accuracy with low metal loss
- Simple operation with reduced labor dependence
- Easy integration into automated production lines
- Wide adaptability to different material sizes
For customers planning long-term operation and cost control, machine-based separation is a more sustainable solution.
Operation and Control Designed for On-Site Use
Intelligent Control System
The eddy current aluminum separation is equipped with an intelligent touch-screen control cabinet and frequency conversion control, providing smoother and more reliable operation. Key transmission components use imported bearings, suitable for long-term continuous use.
One-Button Start for Easy Operation
With one-button automatic control, the machine is easy to start and operate. Precision manufacturing and special processing techniques help reduce noise and vibration during operation, making it suitable for workshop environments.
Magnetic System Protection
The magnetic roller is designed with an effective magnetic system protection structure, preventing magnetic system detachment during high-speed operation and ensuring long-term safety.

Integration into a Complete Metal Crushing and Sorting Line
In many projects, the eddy current separator is not used as a standalone machine but integrated into a complete metal crushing and sorting line, which is also commonly referred to as an aluminum breakage (thermal break aluminum) crushing and sorting line.
Based on different material conditions, the typical process flow is:
metal shredder → metal crusher → eddy current separator → dry grinding mill (polishing and rust removal).
In this line, the metal shredder machine is responsible for primary size reduction of bulky scrap materials, followed by the metal crusher for further crushing and liberation. The eddy current aluminum separation then plays a key role in separating aluminum, copper, and other non-ferrous metals from mixed materials. Finally, the dry grinding machine is used for surface polishing and rust removal, improving the cleanliness and appearance of the recovered metals.
As a supplier, we help customers configure this complete line according to their material type, output requirements, and downstream application needs, ensuring stable operation and effective separation throughout the entire process.
How We Help You Choose the Right Aluminium Eddy Current
As an equipment supplier, our focus is not only on selling machines but on ensuring that the eddy current aluminum separation truly matches your material characteristics and capacity requirements. In practice, an eddy current sorter is usually a key part of a complete recycling line rather than a standalone unit.
Based on your material type, particle size, throughput, and upstream and downstream equipment, we can help you select the appropriate model and provide a stable, long-term separation solution.
If you are evaluating an eddy current separator or would like to discuss its performance with your specific materials, feel free to contact us for more practical and targeted recommendations.
