Overview
This Counter-Parallel Twin-Screw PVC Pelletizing Line is a specialized industrial extrusion system developed by jwell, dedicated to large-scale, high-consistency PVC pellet production. The complete line is composed of a high-precision counter rotating parallel twin-screw extruder and an integrated downstream pelletizing unit, built to solve core challenges of industrial manufacturers: batch-to-batch inconsistency, low production efficiency, and high operating costs in large-volume PVC pellet manufacturing.
Optimized for full-category soft PVC and rigid PVC formulations, this line adopts a fully integrated die-face cutting, air conveying, vibration classification and cooling system. It produces uniform, dense, high-quality PVC pellets with excellent appearance, while achieving high automation, low energy consumption, and uninterrupted production performance, perfectly matching the needs of continuous industrial mass production.
Core Advantages of the Counter-Parallel Twin-Screw PVC Pelletizing Line
Precision Counter-Rotating Parallel Twin-Screw Extrusion Technology
The core parallel twin-screw structure features a constant screw channel depth and uniform shear rate, delivering gentle and efficient plasticizing for heat-sensitive PVC materials. The counter-rotating design ensures excellent dispersion and distribution mixing effect, perfectly adapting to complex modified PVC formulations, and guaranteeing ultra-high batch consistency for long-term mass production.
Closed-Loop Integrated Pelletizing & Processing System
The downstream unit realizes fully closed-loop production from melt extrusion to finished cooled and classified pellets, eliminating cross-contamination and manual intervention in the whole process. This design achieves a near 100% finished product rate, greatly improves production continuity, and reduces production loss for industrial clients with high-volume production demands.
Energy-Saving & Low-Maintenance Industrial Design
The whole line is equipped with a high-efficiency energy-saving main motor, which reduces power consumption while ensuring stable output. The core components are made of high-strength wear-resistant and corrosion-resistant materials, extending service life, minimizing unplanned downtime and maintenance costs, and adapting to high-intensity 7×24 hour industrial operation.
