High Torque Co-rotating Twin Screw Compounding Extruder with 40 Nmcm3 Specific Torque 600kW Drive

HPL75 High Torque Co-rotating Twin Screw Compounding Extruder

The HPL75 is engineered for demanding compounding applications requiring exceptional torque density and reliable 24/7 operation. Combining a double side symmetrical drive gearbox with 40 N*m/cm³ specific torque, this machine delivers 3x the torque performance of conventional twin screw extruders.

Core Features

• Double Side Symmetrical Drive Gearbox — Self-developed load-sharing transmission ensures balanced force distribution across twin screws. Equipped with imported SKF heavy-duty bearings and precision carburized gears, achieving 72,000 working hours service life. Built-in torque overload protection prevents screw and gearbox damage from sudden material blockage.
• Ultra-high Torque Extrusion — 40 N*m/cm³ specific torque enables low-speed high-torque plasticization and high-speed high-yield production. No overload shutdown during high-filler feeding. 600kW frequency conversion direct drive reduces power consumption by 15%-25% compared to traditional single-drive models.
• Wear-resistant Modular Barrel & Screw — High-strength alloy screw shaft matches heavy-torsion working conditions. Imported wear-resistant alloy screw elements and integral hard alloy barrel adapt to glass fiber reinforced, high-powder filled and corrosive materials. Modular design supports quick formula switching and easy cleaning.
• Intelligent PLC Control System — Industrial touch screen enables full-line centralized control of feeding, temperature, vacuum and pelletizing. Supports formula one-click storage, real-time data monitoring, multi-safety alarm and remote fault diagnosis.

Key Applications

This machine employs low-shear low-temperature mixing technology to prevent thermal decomposition of heat-sensitive materials, ensuring uniform dispersion and stable pellet quality. Covers wide application scenarios including high-filled masterbatch, color masterbatch, glass fiber reinforced engineering plastics, PLA/PBAT biodegradable compounding, flame-retardant functional plastics and modified recycled plastics.

Why Choose HPL75?

With premium quality and competitive after-sales cost, the HPL75 serves as a cost-effective alternative to European imported extrusion equipment for global plastic processing enterprises seeking high torque performance and energy efficiency.
