Petrochemical Powder To Pellets Twin Screw Compounder
Description
Performance & Advantages

High Torque Twin-screw Extrusion System
High-torque gearbox:
handle highly filled, high-viscosity materials with ease.
Modular screw design:
screw configuration can be flexibly adjusted for different formulations, giving you precise control over shear intensity and mixing quality.
Wear- and corrosion-resistant materials:
the screw and barrel are made from 40CrMoTi alloy steel, treated with nitriding and a bimetallic spray coating for outstanding long-term durability.


High-precision Measurement and Control:
Multiple loss-in-weight gravimetric feeders and precision liquid additive dosing system:
ensuring consistent metering accuracy.
Siemens PLC control with a 15-inch touchscreen:
delivers temperature control within ±0.5℃ and closed-loop synchronization of main motor speed, feed rate, and pelletizing speed.
Intelligent production management system:
provides real-time production data monitoring, with full support for data recording, storage, and traceability.
Twin Screw Compounder High-efficiency Exhaust System
3–5 independent vacuum vents:
effectively remove residual moisture and volatiles.
Special vent design with a self-cleaning structure:
prevent material overflow and boosts devolatilization efficiency.


Multiple Pelletizing Options
Underwater pelletizing system:
ideal for sticky, tacky materials; produces smooth, dust-free pellets with the high output.
Air-cooled die-face pelletizing system:
suits most general-purpose modified compounds; simple to operate and easy to maintain.
Strand pelletizing system:
well-suited for small-batch, multi-variety production; enables fast product changeovers.

Twin Screw Compounder Application
Powder pelletizing:
blends polyolefins, engineering plastics, and other powders with additives, then pelletizes them directly for easier transport, storage, and downstream processing.
Powder modification:
base powders like calcium carbonate, talc, starch, and wood flour are modified through filling, reinforcement, toughening, or alloying in a twin-screw extruder, producing specialty compounds for biodegradable plastics, wood-plastic composites, automotive, and home appliance applications.
