PE Modified Twin-Screw Granulator Product Introduction

The PE modified twin-screw granulator is designed for high-efficiency compounding and pellet production of polyethylene (PE) based modified materials. It is widely used in industrial plastic modification lines where stable output, strong dispersion performance, and low energy consumption are critical for production cost control and product quality.This equipment is especially suitable for filled PE, reinforced PE, and functional masterbatch production, helping manufacturers achieve consistent pellet quality and stable large-scale output.

1. Output Capacity
* High-torque twin-screw system ensures stable continuous output
* Flexible capacity range to match different production scales
* Optimized screw design reduces material backflow and improves throughput stability

2.Screw Design
* Modular co-rotating twin-screw structure with customizable elements
* Combines conveying, melting, kneading, venting, and homogenizing sections
* Adjustable shear level:
* Low shear for basic blending
* High shear kneading blocks for strong dispersion

3.Material Compatibility

Suitable for:

* PE + CaCO₃ / talc / BaSO₄ filled compounds

* Glass fiber reinforced PE

* Flame-retardant and functional PE materials

* Stable processing of different viscosities and filler loadings

4.Energy Consumption

* High-efficiency gearbox reduces transmission loss
* Optimized heating zones improve thermal efficiency
* Starvation feeding avoids unnecessary screw load

5. Process Design & Operating Principle

Temperature Control Strategy
The melting zone temperature is typically set 10–20°C higher than the PE melting point, ensuring:
* Complete plasticization of polymer
* Uniform filler dispersion
* Reduced unmelted particles and defects

6. Feeding System

* Feed rate and screw speed controlled independently
* Precise control of residence time and filling ratio
* Prevents overloading and improves process stability

7. Technical Advantages

* Co-rotating intermeshing twin-screw design for strong mixing
* Modular screw & barrel for easy customization and maintenance
* High-torque drive system for stable high-load operation
* Vacuum venting system for improved material purity
* Intelligent temperature and pressure control system
* Compatible with strand / water-ring / underwater pelletizing systems

8. Typical Applications

* Filled PE compounds (CaCO₃, talc, BaSO₄)
* PE masterbatch production
* Glass fiber reinforced PE materials
* Flame-retardant and functional polyethylene compounds
* Packaging materials, pipes, sheets, and injection molding grades

9. Production Benefits

* Higher and more stable output capacity
* Improved dispersion quality and mechanical strength
* Lower energy consumption per ton of product
* Strong adaptability to different PE formulations
* Reduced production instability and waste rate
