High-Efficiency PA66 Nylon Fiber Recycling Production Line: A Turnkey Solution from Bulk Material to High-Quality Recycled Pellets
With the tightening of global circular economy regulations by 2025, closed-loop recycling of PA66 (Nylon 66) fiber waste has become an urgent need for the automotive and textile industries. As a leader in plastic recycling technology, ACERETECH recently successfully delivered a customized PA66 fiber shredding, compacting, and pelletizing production line to a South American customer, providing a complete solution for the regeneration of high-toughness synthetic fibers.
Why Choose a Dedicated PA66 Recycling System?
PA66 fibers have high strength, high toughness, and are heat-sensitive. Traditional pelletizing equipment often faces challenges such as difficult feeding, rapid screw wear, and declining output. The ACERETECH solution, through the dual-machine linkage of "DTS shredding + ACS-H compacting and pelletizing," perfectly solves these problems.
For large-volume, high-strength PA66 fibers, the DTS series shredder performs exceptionally well:
Extra-large rotor design: A 600mm rotating diameter rotor provides immense cutting force, allowing it to directly process large bundles of waste fibers.
Low-energy shredding: Through optimized blade arrangement, it reduces energy consumption by 15% while ensuring uniform output size, laying the foundation for subsequent extrusion.
The ACS-H series integrates compacting and pelletizing, specifically designed for low-bulk-density materials like PA66:
1200L intelligent compacting chamber: Achieves rapid cutting, preheating, and compacting of materials in a large-volume chamber, greatly improving the feeding efficiency of lightweight fibers.
160mm dual-alloy wear-resistant screw: Designed to withstand the abrasive nature of PA66, using high-grade dual-alloy material, guaranteeing no significant decline in output within 2 years, significantly reducing maintenance costs.
Vacuum Degassing and Piston Filtration: Equipped with a high-displacement vacuum pump to remove moisture and impurities, and combined with a dual-station, non-stop piston filter, ensuring the production of high-purity, pore-free recycled granules without interrupting production.
Automated Control: One-button start/stop system and intelligent overload protection ensure long-term stable operation of the production line.
2025 Case Study: South American PA66 Recycling Project
After commissioning in February 2025, this customer not only solved the problem of processing factory scraps, but their produced pelletized products, due to their aesthetically pleasing appearance and performance close to virgin material, have been successfully reused in the production of high-end automotive parts.
FAQ
Q1: Why does PA66 fiber recycling require a specialized shredder instead of a regular crusher?
A: PA66 fibers have extremely high toughness and tensile strength. Regular crushers are prone to problems such as "bearing entanglement" or "overheating and damage to the blades." Aisrite's DTS disc-type shredder uses a large-diameter rotor (600mm) and a special blade arrangement to efficiently cut bundles of fibers into small pieces. This not only prevents material entanglement but also improves the feeding stability of the downstream granulator through pre-processing.
Q2: How does Aisrite ensure the durability of its equipment against the abrasive nature of nylon (PA66)?
A: PA66 is a high-hardness, easily worn engineering plastic. Our ACS-H pelletizer is equipped with a 160mm high-quality dual-alloy wear-resistant screw. The surface of this screw undergoes special hardening treatment to resist the physical abrasion of nylon fibers. Aisrite guarantees that, under standard operation, this core component will maintain its production capacity for two years, significantly reducing the user's spare parts replacement costs.
Q3: How to solve the problem of bubbles and pores in granules produced during PA66 fiber recycling?
A: Nylon fibers are highly hygroscopic. If moisture and gases are not completely removed during the recycling process, pores will appear inside the recycled granules, affecting the strength of the finished product. Aisrite's solution includes a high-efficiency vacuum pump system for powerful degassing in the extrusion section; combined with a dual-station non-stop piston filter, it ensures that the material is filtered under high pressure and dense conditions, thus producing dense, pore-free, high-quality granules.
Q4: What practical benefits does the 1200L compaction chamber volume provide for production efficiency?
A: PA66 fibers have a very low bulk density (large volume, light weight), making conventional feeding methods extremely inefficient. Our 1200L extra-large compaction chamber allows for the input of more material at once. High-speed rotating blades pre-cut, pre-heat, and compact the light fibers, instantly transforming them into a high-density material flow, which is then forcibly fed into the extrusion screw. This results in a production increase of approximately 20%-30% compared to traditional feeding methods.
Q5: How automated is your PA66 recycling line? Does it require multiple operators?
A: Our production line integrates an intelligent control system, supporting one-button start/stop and full-line linkage. The system has comprehensive self-protection and warning functions (such as automatic shutdown in case of overload, temperature control warnings, etc.). Thanks to this highly automated design, the entire production line requires only 1-2 workers to monitor the process from feeding to pelletizing, significantly saving labor costs and reducing the risk of operational errors.
