Let’s begin with an overview of this advanced PET flake recycling solution. This system integrates the 10,000 Gauss High-Strength Magnetic Conveyor and the Concentric Eddy Current Separator, designed to achieve exceptional purity in recycled PET materials.
The control panel ensures safe and efficient operation. It features an emergency stop button for quick shutdown, function-specific buttons for precise control, and neatly arranged internal wiring made with renowned-brand components for reliability and durability.
Now, let’s move on to the test run with PET flakes. To demonstrate the machine’s capabilities, we’ve added a mix of contaminants: aluminum flakes and stainless steel springs, which are commonly found in recycling streams.
We’ve mixed these materials thoroughly with the PET flakes to simulate a real recycling scenario. Next, we’ll start the machine to show how it separates these impurities.
Here, you can see the Concentric Eddy Current Separator efficiently separating the PET flakes and aluminum fragments, directing them into their respective collection bins. The results speak for themselves: clean PET flakes in one bin and aluminum flakes in the other.
So, where do the stainless steel springs go? They are separated at the front end by the high-strength magnetic drum, which effectively captures weakly magnetic materials like these springs. This ensures they are removed early in the process.
As you can see, each material is neatly sorted into its designated bin, achieving precise separation and ensuring the purity of PET flakes.
Next, let’s test the system with PET bottles and aluminum cans.
The machine directs the bottles and cans into their respective bins efficiently. However, while this system is capable of handling such tasks, we recommend a combination of de-ironing systems and eccentric eddy current separators for optimal results with PET bottles.
This equipment is ideal for PET flakes, offering precise separation of metals and ensuring high material purity.

Frequently Asked Questions
How does the eddy current separator remove metals from PET flakes?
The system works in two stages. First, a 10,000 Gauss high-strength magnetic conveyor captures ferrous and weakly magnetic contaminants — such as stainless steel springs — at the front end. Then the concentric eddy current separator ejects non-ferrous metals like aluminum flakes with a repelling magnetic force, directing clean PET flakes and separated metals into their respective collection bins.
What contaminants can this system separate?
The demonstration shows it separating aluminum flakes and stainless steel springs mixed into PET flakes, plus aluminum cans from PET bottles. The magnetic stage handles ferrous and weakly magnetic pieces, while the eddy current stage targets non-ferrous metals. This combination covers the metal contaminants most commonly found in post-consumer PET recycling streams.
Why combine a magnetic conveyor with an eddy current separator?
Each stage targets a different metal type. Removing ferrous and weakly magnetic materials first protects the eddy current separator and prevents those pieces from interfering with non-ferrous ejection. The two-stage arrangement is what delivers the exceptional purity shown in the test — clean PET flakes in one bin, aluminum in the other.
Can the system process whole PET bottles and aluminum cans?
Yes — the video also demonstrates bottles and cans being directed into their respective bins. However, for optimal results with whole PET bottles we recommend a combination of de-ironing systems and eccentric eddy current separators, which are better tuned to the size and behavior of whole containers than the concentric unit shown here.
Where does metal separation fit in a PET recycling line?
It typically sits after flaking and washing, where metal contaminants liberated from the bottles need to be removed before drying and pelletizing. Even small metal pieces can damage granulator blades, clog melt filters, or degrade pellet quality, so high-purity separation at this stage protects every downstream machine and the value of the final product.
What should I consider when sizing a separation system?
Key factors are your throughput in kg/h, the particle size of your PET flakes or bottles, and the types of metals in your stream — ferrous, weakly magnetic, non-ferrous, or a mix. Belt width, magnet strength such as the 10,000 Gauss unit shown, and whether you need concentric or eccentric eddy current separation all follow from those inputs.
