A screen changer is essential for removing impurities and ensuring the continuity of plastic pelletizing lines. This guide analyzes selection criteria based on pelletizing methods: double-column continuous types for pressure-sensitive underwater cutting, single-plate double-station for economical strand pelletizing, and backflush systems for high-impurity recycling. By matching filtration area and pressure stability to specific material viscosities and output requirements, manufacturers can reduce downtime by 70% and significantly enhance the purity of the final pellets. Nanjing Haisi Extrusion provides customized filtration solutions to ensure seamless, high-yield production across all compounding and recycling applications.

Based on the two processes of strand pelletizing and underwater pelletizing, we try to analyze seven common granulation problems and the corresponding solutions, and provide some suggestions for continuous mass production of quality products.
