Fire-Resistant PVC Cable Granule Two-Stage Extrusion Line

The High-Efficiency Two-Stage Extruder by JCD is a professional-grade processing equipment optimized for high-moisture, high-impurity recycled plastic regeneration and high-filling plastic modification. Its unique hybrid design combines a high-speed parallel twin-screw extruder (first stage) with a low-speed single-screw extruder (second stage), solving the industry difficulty points of insufficient plasticizing, poor devolatilization and unstable product quality in waste plastic processing.
Covering a combined output range of 100-1500kg/h, this extruder leverages the high dispersion of twin screws for rapid material melting, while the single screw ensures low-temperature, stable extrusion to avoid thermal decomposition. Its vertical compact layout saves workshop space and supports continuous, large-scale production lines, making it the core equipment for plastic recycling enterprises and high-filling modification manufacturers.

Note: All parameters can be customized according to your recycled plastic processing capacity and production line design.

✅ Dual-Stage Synergy for Efficient Regeneration

• First Stage (High-Speed Twin Screw): High dispersion and strong shear force rapidly plasticize and disperse high-impurity waste plastics (e.g., PE/PP films, mixed waste). The modular screw design can be adjusted for different materials to achieve optimal mixing.
• Second Stage (Low-Speed Single Screw): Single-head deep groove structure stabilizes melt pressure, while precise heating/cooling controls extrusion temperature to avoid material decomposition, ensuring stable product quality.

✅ Enhanced Devolatilization & Impurity Removal
The twin-screw stage efficiently removes moisture and volatile gases from recycled materials, while the single-screw stage further homogenizes the melt, eliminating hollow pellets and ensuring compact, high-quality finished products.
✅ Space-Saving Vertical Layout
The vertical arrangement of the two extruders reduces floor space by 30% compared to horizontal designs, enabling a streamlined continuous production line layout for large-scale recycling projects.
✅ Energy Efficient & Cost Effective
Optimized power matching and low-temperature extrusion reduce unit energy consumption by 15-25% compared to single-stage extruders, lowering long-term operating costs for recycling enterprises.

This extruder is dedicated to recycled plastic processing and high-difficulty modification scenarios, widely used for:

• Recycled Plastic Regeneration: PE/PP film recycling, PVC pipe regeneration, mixed waste plastic processing, and PA/PC engineering plastic recycling.
• High-Filling Plastic Modification: Talc/calcium carbonate filled PP/PE, flame-retardant modified plastics, and functional masterbatch production.
• Large-Scale Continuous Production: Supporting 24/7 continuous operation for plastic recycling plants and modified plastic manufacturers.
