I. Industry Challenges: Why PE High-Filling Compounding Difficult?
In the field of plastic compounding, as the filling ratio of calcium carbonate (CaCO₃) rises to 30%, traditional pelletizing equipment will face bottlenecks:
High Filler Ratio → Reduced Melt Flowability
Poor Dispersion → Unstable Pellet Performance
High Wear & Tear → Shorten Equipment Lifetime
Increased Thermal Sensitivity → Easy Degradation and Yellowing
👉 The Core Contradiction: achieve both a high filling ratio and stable, high-quality production.
II. Solution: The ATE Parallel Twin-Screw Pelletizing System
ACERETECH ATE series of parallel twin-screw pelletizing machines is specifically optimized for high filler masterbatch compounding and pelletizing applications. It is able to stably processing PE flakes with 30% CaCO₃, enabling efficient, continuous, and controllable industrial-scale production. By optimizing the screw structure, feeding system, and temperature control system, the ATE system achieves the following under high-filler conditions:
✔ Efficient Dispersion: Ensures uniform distribution of calcium carbonate within the PE flakes
✔ Stable Feeding: Prevents bridging and feeding fluctuations.
✔ Continuous Production: Reduces downtime and boosts production efficiency.
✔ High-Quality Pellet Output: Produces uniform pellets with stable performance.

FAQ
Q1. What are the biggest challenges involved in materials adding 30% calcium carbonate filler content?
A: The primary challenges are reduced flowability and increased difficulty in dispersion; additionally, it tends to cause equipment wear and melt instability.
Q2. Why use a twin-screw extruder rather than a single-screw extruder?
A: Twin-screw extruders present superior shearing and kneading capabilities, enabling the uniform dispersion of high-filler systems— that is difficult to achieve with single-screw extruders.
Q3. How does the ATE system ensure effective dispersion?
A: By optimizing the screw configuration (specifically, the combination of kneading blocks and dispersion elements) and precisely controlling shear intensity, the system ensures the uniform distribution of fillers.
Q4. Will high-filler materials reduce the equipment's service life?
A: Yes, they can; however, the ATE system utilizes wear-resistant materials and an optimized structural design to significantly extend the equipment's service life.
Q5. Does this system support even higher filler ratios?
A: Yes, it does. Based on the specific material properties and processing requirements, the screw configuration can be customized to accommodate even higher filler ratios.
