PET Chip Treating Line

Featured Technology

Floating Gravity Separator
  • Proprietary technology of Siontech
  • For removing heavy impurities
    • 1 Rotating strainer nets shake surface of water containing light PET fine chips and heavy impurities.
    • 2 The strainers separate floated PET fine chips and transfer them to the next unit.
    • 3 Heavy impurities are discharged by sinking to the bottom.
  • Continuous process
