PURUI Single Screw Recycling Granulation Machine for HDPE Rigid Flakes

Application of PURUI Single Screw Recycling Granulation Machine for HDPE Rigid Flakes:
The PURUI SJ series single screw granulator is designed for processing a wide range of materials such as crushed rigid plastics, bottle flakes, and agglomerated films. This advanced granulation system features a unique screw design, efficient degassing and filtration (hydraulic screen changer) system, ensuring stable performance and long-lasting durability. The machine is highly automated, requiring only two workers to operate the entire production line — one to manage the control panel and another to feed the materials and change the hydraulic screen.
 
Technical Advantages
  • Enhanced material intake with greater flexibility and higher throughput capacity
  • Preconditioning unit ensures optimal material preparation for the extruder
  • Hot die face pelletizing system with direct drive technology — state-of-the-art pelletizing solution
  • Liquid-cooled extruder for precise temperature control in different zones, resulting in high-quality melt processing
  • Large-area ultra-fine filtration standard
  • Innovative and patented technologies in the preconditioning unit
