### Application
The TSE-75/180 PVC granulating machine is ideal for processing soft PVC and rigid PVC for use in pipe manufacturing, wire coating, and more. This system ensures high-quality output with consistent performance.
---
### Features
The first stage features a TSE twin-screw extruder without a die. This allows for effective melting, compounding, and dispersion of thermosensitive materials like PVC under low-pressure conditions. The second stage is a single-screw extruder (SJ180), which operates at a lower speed to ensure steady melting, long-term compounding, and strand formation, reducing the risk of overheating.

### Granulating Line
An air-cooled hot-face pelletizing line is used for PVC granulation. This system ensures high efficiency and quality during the pelletizing process.
