In an era where plastic circularity demands higher precision, Purui Machinery is redefining industry standards with its material-specific customized plastic recycling solutions. By moving away from generic equipment, Purui provides engineered systems that address the unique chemical and physical profiles of different plastic wastes.

Plastic Recycling Solutions for Different Materials:

• PE/PP Soft Plastics (Films/Woven Bags): For highly contaminated agricultural or post-consumer films, Purui’s ML series plastic granulator features an integrated cutter-compactor. This plastic granulation system pre-dries and densifies the material before extrusion, effectively handling high-moisture feedstocks while optimizing energy efficiency.

• PET Flakes (Bottle-to-Bottle/Fiber Grade): PET has extremely high requirements for viscosity and color. To address this, Purui integrated a new deep drying process with a vacuum system. This significantly improves granule color and ensures a viscosity of ≤0.05. As a result, the granules are suitable for filament production and food-grade packaging.

• Rigid Plastics (ABS/PS/PC): Purui offers customized single and twin-screw granulation lines for E-waste and automotive scrap. These lines focus on intense degassing and fine filtration. By removing odors and impurities, the system restores the mechanical properties of engineering plastics for high-value reuse.

• Non-Woven & Fibers: Specialized feeding systems are tailored for low-bulk-density materials, preventing “bridging” in the hopper and ensuring a continuous, stable production flow.

Purui’s Suggestion:

“Every plastic has a unique ‘DNA’—from its melting point to its contamination level,” says the Technical Director of Purui Machinery. “Our engineering team conducts a deep-dive into the customer’s specific material source and end-product goals. Whether it’s a custom screw design or a multi-stage filtration setup, we build the plastic pelletizing machine around the material, not the other way around.”

FAQ:

Q1: How does Purui handle high-moisture materials like washed PE agricultural films?

A: Our ML Series uses an integrated cutter-compactor for efficient pelletizing. Frictional heat pre-dries and densifies materials before they reach the extruder. Consequently, the system maintains stable throughput while eliminating the need for extra drying equipment.

Q2: Can your PET recycling lines produce food-grade pellets?

A. Yes. By combining our multi-stage high-temperature washing modules with a Liquid State Polycondensation (LSP) system, we effectively remove contaminants and restore Intrinsic Viscosity (IV) to meet food-contact standards.

Q3: Is it possible to switch between different materials on the same pelletizing line?

A. While our pelletizing lines are optimized for specific polymers, we offer modular screw and die-face designs. By swapping specific components and adjusting the PLC process parameters, customers can achieve the flexibility to process related material groups (e.g., HDPE and PP).
