Multi-stage machine granulation unit

High-Efficiency Three-Stage Plastic Granulation Line

Product Overview

The Three-Stage Screw Pelletizing Unit represents the pinnacle of large-scale plastic recycling and compounding technology. By integrating multiple extrusion stages, this system provides enhanced filtration, superior degassing, and unmatched homogenization. It is specifically engineered to handle highly contaminated post-consumer plastics or complex polymer blends that require intensive processing.

Core Technical Advantages

• Multi-Stage Filtration & Purity: The three-stage design allows for sequential filtering, ensuring that the final pellets are of the highest purity even when starting with heavily soiled feedstock.

• Enhanced Degassing Performance: Multiple vacuum degassing ports along the three screw sections effectively remove moisture, ink residues, and volatile impurities, resulting in solid, bubble-free pellets.

• Optimal Plasticization: Each stage can be customized with specific screw geometries (Twin or Single) to provide the perfect balance of shearing and temperature control for different materials.

• High-Torque Durability: Built with heavy-duty gearboxes and high-performance motors, the unit is designed for 24/7 industrial operation with minimal downtime.

• Intelligent PLC Control: The entire line is synchronized through a centralized control system, allowing operators to monitor temperature, pressure, and flow rates across all stages in real-time.

Typical Applications

• Challenging Recyclables: Processing washed PE/PP films, woven bags, and crushed rigid plastics with high residual moisture.

• Complex Compounding: Ideal for high-filler masterbatches or polymer alloys requiring multiple mixing stages.

• Large-Scale Production: Designed for manufacturers requiring high-output consistency and stable pellet quality.
