50-1000 kg/h Waste PET Flake Pelletizing Granulator Line Pelletizer Granulating Machine
By MOOGE TECH. Recycling Machinery
Summary
## Key takeaways - **Pre-Crystallization Drying Essential**: The pre-crystallization drying Tower thoroughly dries and softens the PET flakes, significantly reducing the hydrolysis of the molecular chains during the extrusion process. This ensures that the intrinsic viscosity of the final recycled polyester pellets remain stable. [00:43], [01:04] - **Twin Screw Minimizes IV Drop**: PET material is prone to hydrolysis at high temperatures, so a twin screw design is ideal for processing it, allowing the material to be processed at a lower temperature minimizing the drop in IV. It utilizes excellent mixing and shearing capabilities to control the viscosity effectively. [01:15], [01:25] - **Hydraulic Filter Screen Changes**: The filtering die head features hydraulic control enabling screen changes without stopping production. [01:57], [02:07] - **Water Ring Pelletizing Reduces Waste**: Unlike traditional strand pelletizing methods we employ a more user-friendly water ring pelletizing process. The molten material is directly fed into the pelletizer by water flow reducing waste during manual strand pulling. [02:07], [02:18] - **Produces High-Quality Transparent Pellets**: Finally the pellets are dried and transported via an air conveying system resulting in high quality transparent rPET pellets.

[Music] hello everyone this is Mo today I'd like to introduce our pet pelletizing equipment the parallel twins screw
Extrusion pelletizing line this pelletizing line is specially designed for processing washed IP flakes converting waste pet box into recycled
polyester pellets these pellets are widely used in producing recycled polyester sheets boards and filaments playing a crucial role in promoting pet
plastic recycling the first equipment in the production line is the pre-crystallization drying Tower this equipment thoroughly dries and softens the epet
flakes significantly reducing the hydrolysis of the molecular chains during the extr us process this ensures that the intrinsic
viscosity four of the final recycled polyester pellets remain stable the pre-crystallization drying Tower is essential for producing highquality
recycled polyester pellets next is the twin screw extruder pet material is prone to hydrolysis at high temperatures
so a twinc screw design is ideal for processing it the twin screw extruder allows the material to be processed at a lower temperature minimizing the drop in
four additionally it utilizes excellent mixing and shearing capabilities to control the viscosity effectively additives can also be introduced to
enhance the viscosity of the Recycled polyester pellets the third step involves the Extrusion of the molten material through the filtering die head
where it is solidified in a cooling water water tank our filtering die head features hydraulic control enabling screen changes without stopping
production unlike traditional strand pelletizing methods we employ a more userfriendly water ring pelletizing process the molten material is directly
fed into the pelletizer by water flow reducing waste during manual strand pulling finally the pellets are dued
dried and transported via an air conveying system resulting in high quality transparent repet pellets this concludes the detailed introduction of
our parallel twin screw Extrusion pelletizing line if you'd like to learn more about specifications and pricing
