**Application:**
The SP-75/180 PE compound with CaCO3 granulating machine is ideal for high filler masterbatch, soft PVC, and rigid PVC applications. It’s widely used in pipe manufacturing, wire coating, and similar industries.
**Machine Design:**
The first stage consists of a TSE twin-screw extruder without a die, which is optimized for melting, mixing, and dispersing thermosensitive materials like PVC under low pressure conditions. The second stage uses an SJ single-screw extruder, which operates at lower speeds to ensure stable melting, compounding, and strand formation while preventing overheating.
**Granulating Line:**
An air-cooled hot face pelletizing line is used for high-filler masterbatch, ensuring efficient and consistent pellet production.
