PP/PE Two-Stage Pelletizing Line
**Application & Features:**
The PP/PE two-stage pelletizing line is designed for efficient processing of thermoplastic materials such as polypropylene (PP) and polyethylene (PE). The first stage involves a SHJ twin-screw extruder without a die, which allows for effective melting, compounding, dispersion, and decentralization of sensitive thermoplastic materials like PVC under no backpressure conditions. This ensures high-quality mixing and homogeneity. The second stage uses a single-screw extruder (SJ series), which operates at a lower rotational speed. This helps in achieving stable melting, long-term compounding, and consistent strand formation, preventing overheating and degradation of the material. Ningbo Mengkwa Machinery Co., Ltd. has been a professional manufacturer of plastic extruders and extrusion lines for many years. We specialize in producing a wide range of equipment, including plastic pipe extrusion lines, profile extrusion lines, sheet/plate extrusion systems, and recycling and pelletizing machines. Our experienced engineers provide customized mechanical designs and advanced processing technologies to meet the specific needs of our customers. **Main Technical Parameters:**
**Additional Information:**
