The Mag Spring® Plastic Pellet Iron Removal System is a high-intensity magnetic separator for plastic pellet iron removal, engineered to efficiently remove ferrous contaminants，including iron embedded inside plastic pellets from plastic pellets, granules, and bulk materials. Each system incorporates rare earth neodymium magnets embedded in durable stainless steel grids, providing superior separation performance while maintaining hygienic, easy-clean construction.
This plastic pellet iron removal system is widely used in food processing, plastic recycling, chemical industries, and pharmaceutical production lines. Its flexible design ensures compatibility with hopper, chute, and conveyor installations.
Plastic Recycling & Compounding Lines
Protects extruders, grinders, and feeders from iron contamination.
Chemical & Powder Processing
Removes ferrous particles from powders and granular materials efficiently.
Conveyor & Hopper Integration
Magnetic separators for plastic pellet iron removal can be installed directly into existing lines.
When iron impurities are embedded inside plastic pellets, traditional magnetic bars or grids fail to remove them effectively.
Our penetration-type magnetic separation system is specifically engineered to remove deeply embedded micro iron particles in plastic granules — ensuring maximum product purity, longer equipment life, and fewer customer complaints.
✅ 100+ Successful Installations Worldwide
✅ Proven Efficiency in Plastic Recycling, Extrusion & Masterbatch Lines
✅ Designed for Continuous, Automatic Operation
Pain Points for Plastic Manufacturers:
👉 You need a magnetic separator for plastic granules with deep magnetic field penetration — not just surface attraction.
Core Principle:
Unlike traditional magnetic separators, this system utilizes a combination of high-intensity NdFeB magnetic drums and plates to create a multi-layered magnetic field that penetrates deep into the pellet body.
It effectively attracts and extracts iron particles trapped inside or partially encapsulated by plastic.
System Highlights:
✅ 99.2% Iron Removal Efficiency:
Proven performance in removing fine and embedded ferrous particles from plastic pellets and powder materials.
✅ Handles Multiple Material Types:
Suitable for plastic granules, powder, or mixed materials, ensuring broad adaptability across different polymer production environments.
✅ Sealed & Dust-Proof Construction:
Custom-designed for closed-loop operation, pressure resistance, and dust control, ensuring no secondary contamination in cleanroom or high-purity environments.
✅ Deep Magnetic Penetration:
High-intensity deep penetration magnetic separator ensures precise extraction of hidden or encapsulated ferrous contaminants.
✅ Automatic Operation & Continuous Flow:
Integrates into existing conveyor belt or material handling systems for uninterrupted, maintenance-free performance.
✅ Long-Term Stability:
Built with premium neodymium magnets and corrosion-resistant components, guaranteeing durable performance even under heavy-duty industrial use.
“After installing this system, our product purity improved drastically.
Iron-related defects dropped by 98%, and extruder filter life doubled.”

Yes. The deep penetration magnetic field effectively extracts embedded iron impurities, even those encapsulated within pellets.
Absolutely. It supports plastic powder, pellets, and mixed materials, providing flexibility across various material processing lines.
Yes. We can design sealed, dust-proof, and pressure-resistant configurations to meet the requirements of clean or high-purity production environments.
Independent testing and customer feedback confirm up to 99.2% efficiency.
Yes. The design allows easy integration with conveyor belts, feeders, or magnetic filtration modules in your production line.
Standard magnetic bars only catch surface iron. During the extrusion of plastic pellets, fine iron powder often gets trapped inside the granule. Our deep penetration system uses a high-gradient magnetic circuit to “pull” the iron out from the center of the pellet, ensuring 99.2% purity.

The core efficiency of our system lies in its dual-stage purification process. As plastic pellets are evenly fed via a vibrating feeder onto the conveyor belt and enter the separation zone, they first pass under a high-intensity overhead magnetic plate.
This plate generates a concentrated magnetic field that polarizes both free iron and embedded iron impurities. This polarization causes them to “vibrate” within the polymer matrix, providing enough magnetic lift that a significant portion of pure iron contaminants and plastic pellets containing hidden iron are instantly captured and sucked onto the magnetic plate surface.
For the remaining impurities and encapsulated particles that were not lifted, their internal ferrous elements remain highly magnetized. These particles then encounter a Deep Penetration Flux Field generated by the magnetic drum. The interaction between this powerful external field and the magnetized iron creates a massive “tugging” force. This force effectively attracts and holds both pure iron contaminants and plastic pellets containing hidden iron against the belt surface on the magnetic drum.
At the discharge point, the purified, iron-free plastic pellets fall via gravity into the clean material stream. Meanwhile, the captured iron impurities and iron-bearing plastic granules are carried further by the moving belt until they exit the magnetic field zone, where they are automatically released into a dedicated collection bin. This continuous, multi-stage process ensures a 98% – 99.2% iron removal efficiency without any interruption to your production flow.
Our system leverages advanced Neodymium magnetic separation technology to generate a deep-penetrating magnetic field, capable of extracting even the most stubborn encapsulated ferrous particles, ensuring maximum efficiency in ferrous contamination removal.
