Henglande Launches 75mm High-Torque Twin Screw Extruder with Advanced Underwater Pelletizing System

Nanjing, China — Nanjing Henglande Machinery Technology Co., Ltd. proudly introduces its 75mm high-torque co-rotating twin screw extruder integrated with a fully automated underwater pelletizing system, delivering superior pellet quality, stable high-output performance, and reliable continuous production for demanding compounding applications.

The 75mm twin screw extruder has become one of the most popular models in the global plastic compounding industry due to its balanced combination of output capacity, energy efficiency, and operational stability.

75mm High-Torque Extrusion Platform

The 75mm model features:

• High-torque gearbox design

• Modular screw configuration system

• Wear-resistant alloy steel screws and barrels

• Precision temperature control via PLC system

• Stable feeding and dispersion performance

With optimized screw design and high mixing efficiency, the machine ensures excellent dispersion for fillers, pigments, additives, and reinforcement materials.

Typical output capacity can reach 300–500 kg/h depending on material formulation.

Advanced Underwater Pelletizing System

The extrusion line is equipped with a high-performance underwater cutting system, which cuts molten polymer directly at the die face under water circulation.

Compared to traditional strand pelletizing systems, the underwater pelletizing system offers:

• Perfect round and uniform pellets

• Smooth pellet surface

• Reduced dust generation

• Stable cutting at high throughput

• Better cooling efficiency

• Continuous and automated operation

This makes it especially suitable for:

• High CaCO₃ filler masterbatch

• Black masterbatch

• Engineering plastics (PA, PC, PET)

• Biodegradable materials

• High melt flow polymers

The system ensures consistent pellet size and improved downstream processing performance.

Ideal for Industrial Compounding & Recycling

The 75mm twin screw extruder with underwater pelletizing system is widely applied in:

• Masterbatch production lines

• Engineering plastic modification

• High-output filler compounding

• Recycled PP/PE pelletizing

• High-performance compound manufacturing

Its stable high-output capacity and precision pelletizing technology make it an ideal solution for medium-to-large scale production facilities.
