SJPT Twin Screw Plastic PET Extruder Pelletizer Machine
Description
The SJPT series twin screw extruder is designed specifically for processing clean PET flakes into high-quality granules. This machine is widely used in the production of PET pellets and can also be adapted for other materials such as PP, PE, PA, and ABS. The system includes a SHJ parallel twin screw extruder, die, hydraulic screen exchanger, cooling flume, air dryer, cutter, and silo. It is ideal for recycling and processing plastic waste efficiently.
Structure of PET Flakes Pelletizing Line:
The system consists of two stages: the first stage is a single screw extruder, and the second stage is a low-speed single screw extruder. These two units are arranged vertically to optimize the process flow and improve efficiency.
Advantages of the PET Flakes Pelletizing Line:
1. Enhanced operational flexibility with a two-stage design, allowing for more precise control over the production process.
2. High productivity and output capacity, suitable for large-scale operations.
3. Excellent performance when handling heat-sensitive materials and during devolatilization processes, such as PVC and XLPE.
4. Suitable for processing zero-halogen cables, shielding materials, carbon black, and similar substances.
