What are the core advantages of a granulation line?

Why do customers prefer to choose it?

👉This pelletizing line has been comprehensively upgraded, from structural 

design to material selection-designed for high-quality recycled pellets.

1️⃣ Two-Stage Extrusion System - Dual Filtration for Purer Particles

The entire line utilizes a two-stage extrusion system, meaning two extruders 

operate in series, each equipped with an independent screen changer.

✔ Dual Melting

✔ Dual Filtration

✔ More Thorough Impurity Removal

🔹Especially suitable for recycled materials containing high levels of impurities, 

such as films, printed films, and woven bags.

👉 Cleaner Finished Particles

👉 Fewer Black Spots

👉 More Stable Melting

👉 Significantly Improved Particle Quality

2️⃣ Vacuum Exhaust System - Designed for Moisture-Containing and 

Printed Materials

The first-stage extruder is equipped with a vacuum exhaust system to 

effectively remove:

✔ Water vapor

✔ Ink volatiles

✔ Low-molecular-weight gases

🔹Especially suitable for:

Plastics containing moisture

Printable film materials

Materials containing a small amount of residual moisture after cleaning

3️⃣ High-strength nitrided steel screw and barrel - More wear-resistant 

and durable

The extruder barrel and screw are made of:

High-strength nitrided steel (38CrMoAlA)

Features:

✔ Excellent wear resistance

✔ Good corrosion resistance

✔ Strong high-temperature stability

This means:

👉 Longer service life

👉 Stable long-term operation

👉 Reduced maintenance costs

Truly suitable for continuous industrial production.

4️⃣ Compaction silo with dust removal system - more stable feeding

The compaction silo is equipped with a dust removal system at the top, which 

effectively:

✔ Reduce dust

✔ Reduce impurities entering

✔ Improve the working environment

Also improve feeding stability, resulting in more uniform melting.

5️⃣ Cooling System - Unaffected by Overheating During Long-Term Operation

The cooling tank is equipped with a heat exchanger at the bottom and connects 

to an independent chiller system.

This forms a circulating cooling system:

✔ Rapidly reduces water temperature

✔ Prevents overheating during long-term operation

✔ Maintains stable cooling effect

Advantages include:

👉 More thorough granule cooling

👉 No deformation

👉 No sticking

👉 Improved granule surface quality

Especially crucial for high-volume continuous production.

6️⃣ Vibrating Screen System - Final Quality Control

High-efficiency vibrating screens are used for:

✔ Removing fine powder

✔ Separating defective particles

✔ Improving uniformity

Ensuring final particles are:

👉 Clean

👉 Dry

👉 Consistent particle size

If you wish to:

👉 Improve pellet quality

👉 Reduce after-sales issues

👉 Increase profit margins

This Polish-configured pelletizing line is a more stable option.
