Product details
The SJSZ65/132 is a widely utilized conical twin-screw extruder primarily designed for high-efficiency processing of PVC powder and heat-sensitive materials. Its unique conical geometry provides a large feeding area and superior plasticizing capabilities compared to parallel designs, making it ideal for high-filler applications.
1. Core Technical Specifications
1) Output Capacity: 550 - 600 kg/h, depending on the material formulation.
2) Screw Parameters: Two conical screws with diameters of 65mm (discharge) and 132mm (feeding).
3) Drive System: Equipped with a 30 kW or 37 kW AC motor, often controlled by Siemens or ABB frequency inverters.
4) Heating Power: 20 - 24 kW provided by cast-aluminum across multiple heating zones.
2. Key Structural Features
1) Nitrided Components: The screw and barrel are made from 38CrMoAlA high-quality alloy steel, treated with nitriding or bimetallic coating to ensure extreme wear and corrosion resistance.
2) Advanced Cooling: Features air cooling for the barrel and internal oil cooling for the screw core to maintain precise melt temperatures and prevent material degradation.
3) Vacuum Degassing: Includes a dedicated vacuum pump (typically 1.5 kW) to remove moisture and volatiles, ensuring the final product is free of bubbles and high in density.
4) High-Torque Gearbox: Utilizes a heavy-duty vertical gearbox with hardened teeth ( Jiangyin brand is common) to ensure stable long-term operation under high pressure.
3. Primary Applications
The SJSZ65/132 serves as the core component for several industrial production lines
1) PVC Pipe Production: Manufacturing conduit, water supply (50 - 110mm), and drainage pipes.
2) Profile Extrusion: Creating window frames, door panels, and WPC (Wood-Plastic Composite) profiles.
3) Sheet & Panel Making: Producing PVC marble sheets, decorative wall panels, and foam boards.
4) Pelletizing: Recycling and compounding PVC powder into granules.
