**Application & Features:**
The **Two-Stage Compounding Extruder Pelletizing System** is designed for efficient and high-quality compounding of thermoplastic materials. It consists of two stages: the first stage features an SHJ twin-screw extruder without a die, which is ideal for processing heat-sensitive materials such as PVC. This system ensures effective melting, mixing, dispersion, and deagglomeration under conditions of no back pressure.
The second stage uses an SJ single-screw extruder, which operates at a lower rotational speed. This helps in achieving stable melting, thorough compounding, and consistent strand formation, preventing overheating and ensuring product quality.
