The demand for recycled plastic materials continues to grow as manufacturers seek sustainable and cost-effective production solutions. One of the most challenging materials to recycle is agricultural LLDPE film due to its exposure to dirt, moisture, and contaminants during use. To address these challenges, our 1,000 kg/h Recycled Agricultural LLDPE Pelletizing Line was designed to deliver high productivity, stable operation, and premium pellet quality.
This project, successfully installed in Korea, demonstrates how advanced pelletizing technology can efficiently convert recycled agricultural LLDPE flakes into high-quality plastic pellets suitable for reuse in a wide range of plastic products.
Project Overview
This recycling system is specifically engineered for processing recycled agricultural LLDPE with high efficiency while maintaining excellent pellet consistency.
Project Parameters
- Equipment: Plastic Pelletizing Line
- Material: Recycled Agricultural LLDPE
- Feed Form: Granulated Flakes
- Moisture Content: Approximately 0.1%
- Capacity: 1,000 kg/h
- Final Pellet Size: 3–5 mm
- Air Pressure: Above 0.6 MPa
- Installed Power: Approximately 420 kW
- Project Location: Korea
Complete Production Process
The pelletizing line integrates every stage of the recycling process into one fully automated system, ensuring continuous production with minimal manual intervention.
The production process includes:
- Material feeding
- Material compaction
- Two-stage extrusion
- Continuous melt filtration
- Laser filtration
- Water-ring pelletizing
- Centrifugal drying
- Vibration screening
- Pneumatic conveying
- Finished pellet storage in silo
Each component is carefully matched to maximize productivity while producing clean, uniform plastic pellets.
Advanced Two-Stage Extrusion System
At the heart of the production line are the SJ-160/33 primary extruder and SJ-180/10 secondary extruder.
The first-stage extruder efficiently melts and plasticizes the recycled agricultural LLDPE flakes, while the second-stage extruder further homogenizes the melt, ensuring improved material quality and stable output. This two-stage design reduces fluctuations during production and helps produce pellets with consistent physical properties.
High-Efficiency Filtration for Cleaner Pellets
Recycled agricultural film often contains fine contaminants that can negatively affect pellet quality. To address this challenge, the production line combines multiple filtration technologies.
The system is equipped with:
- 80-mesh continuous screen changer
- 150-mesh dual-plate laser filter
This dual filtration configuration continuously removes impurities from the molten plastic without interrupting production. As a result, the finished pellets exhibit excellent cleanliness, improved appearance, and greater consistency, making them suitable for demanding downstream applications.
Water-Ring Pelletizing for Uniform Granules
Following extrusion and filtration, the molten plastic enters the water-ring pelletizing system.
This technology enables:
- Consistent pellet size of 3–5 mm
- Smooth pellet surfaces
- Stable cutting performance
- High production efficiency
The pellets are then dried by a centrifugal dryer before passing through a vibration screening system to remove oversized or undersized particles. Finally, a pneumatic conveying system transports the finished pellets into a storage silo, completing the automated production process.
Intelligent PLC Control for Reliable Operation
The entire pelletizing line is controlled by a Siemens PLC automation system, providing centralized control and real-time monitoring of all production stages.
Operators benefit from:
- Easy parameter adjustment
- Stable production control
- Automatic fault detection
- Reduced labor requirements
- Continuous, reliable operation
The intelligent control system enhances production efficiency while minimizing downtime and maintenance.
