New PET Fiber and PET Flake Recycling Production Line Equipped With LSP System

ntroducing the latest innovations of Pr-PUlier, a new PET fiber and PET flake recycling production line equipped with LSP system. With over 18 years of experience in the plastic recycling machinery industry, we are proud to introduce cutting-edge solutions that revolutionize the recycling and pelletizing process.

Our new PET fiber and PET flake recycling lines equipped with LSP systems are designed to increase the viscosity of the final pellets and improve the quality of the final product. The pellets could reach the PET fiber quality. By incorporating advanced technology, we create a system that ensures superior performance and efficiency.

Using advanced and reliable process technology and equipment, polyester waste is used as the main raw material, and after drying, it is produced through shredder and extruder single screw melting, filtration and impurity removal, continuous polycondensation and viscosity enhancement and homogenization. Polyethylene terephthalate melt, that is, fiber-grade PET melt, can produce polyester filament staple fibers, recycled chips, strapping tape, polyester film and other products or it just be pelletized. Using polyester waste to produce recycled polyester fiber can reduce costs, reduce oil consumption, and improve economic benefits, which is of great significance to the sustainable development of the chemical fiber industry. PET produced by liquid phase viscosity enhancement has a narrow relative molecular mass distribution, less product by-products, improved product quality and low energy consumption. At the same time, with the growth of recycled polyester volume, the issue of the substitutability of recycled polyester and virgin polyester has also attracted more and more attention from the industry.

The waste textiles are thickened by vertical and horizontal double kettles in series to achieve the reuse of waste textiles. Process introduction: The waste textiles are melt-blended in the screw extruder, and the vertical and horizontal double kettle thickening system is used to achieve the thickening effect. The vertical kettle is a high-temperature and high-vacuum stirring kettle, which makes low molecules and impurities gasified and extracted from the vacuum port, thereby improving the purity of the raw materials and achieving the purpose of primary thickening. The melt after primary thickening is transported to the secondary thickening kettle (horizontal disc reactor) through the melt pump to further extract low molecules and impurities. Under the push of the disc, the melt is transported to the delivery pump and then spun through the filter.

The entire system of reactor liquid phase thickening includes liquid phase thickening reactor, vacuum system, heat medium circulation system and melt delivery system. The key technology lies in the design of the liquid phase thickening reactor. The liquid phase thickening reactor is a single-axis reactor consisting of a horizontal shell and a central stirring shaft. The stirring shaft is equipped with a disc that is perpendicular to it and can rotate with the shaft. The disc is distributed at a certain angle along the axis. When the stirring shaft rotates, the disc rotates with the stirring shaft. On the one hand, it plays the role of mixing, film drawing and conveying, and on the other hand, it can remove the dirt on the surface of the shell.

Our company's viscosity-enhancing reactor adopts a disc reactor. Advantages: The disc reactor uses a whole shaft to connect the discs, which has a stable structure and better strength. It is more suitable for high-viscosity (viscosity reaches 0.85) fluids. Disc reactors have been popularized in high-viscosity fluids.

This state-of-the-art machine features fully automatic operation, making it extremely easy to control and operate. Its high-quality construction and reliable performance guarantee a seamless recycling and pelletizing process. Additionally, the system is designed for easy maintenance, minimizing downtime and maximizing productivity.
