**High Output Two Stage Extrusion Machine for PVC Compounding** This high-output two-stage extrusion machine is specifically designed for the production of PVC granules, including soft and rigid PVC used in pipes, wires, and other applications. The system consists of a twin-screw extruder followed by a single-screw extruder, ensuring efficient processing and high-quality output. **Technical Specifications:** - **Model No.:** SP75/180 - **Engagement System:** Full Intermeshing - **Screw Channel Structure:** Deep Screw - **Exhaust:** Yes - **Automation:** Non-Automatic - **Computerized:** Non-Computerized - **Place of Origin:** Jiangsu, China - **Brand:** Nanjing Haisi - **Power:** 90-110/45-55 kW - **Materials Processed:** PVC, High Filler Masterbatch - **Capacity:** 500-800 kg/h - **Warranty:** 1 Year - **After-Sales Service:** Engineers available for overseas service - **Screw Diameter:** 71 mm; 180 mm - **Screw Rotational Speed:** 65~85 rpm; 400~600 rpm - **Trademark:** Nanjing Haisi - **Transport Package:** Neutral Packing - **Certifications:** CE, ISO9001, SGS - **Origin:** Nanjing, Jiangsu **Application:** The TSE-75/180 PVC granulating machine is ideal for processing soft and rigid PVC materials for pipe, wire, and other industrial applications. It is designed to ensure consistent quality and high productivity. **Features:** The first stage is a TSE twin-screw extruder without a die, capable of efficiently melting, compounding, dispersing, and decentralizing thermosensitive materials like PVC under low-pressure conditions. The second stage uses an SJ single-screw extruder, which operates at a lower speed, allowing for stable melting, longitudinal compounding, and strand formation while preventing overheating. **Granulating Line:** The system includes an air-cooled hot-face pelletizing line suitable for PVC processing. This ensures efficient cooling and shaping of the final product. **About Our Company:** Nanjing Haisi Extrusion Equipment Co., Ltd. is a high-tech enterprise specializing in the R&D, manufacturing, and sales of extrusion equipment.
