double screw extrusion granulator for waste PET bottles flakes.The machine with High-torque twin-screw extruding screw unit, this is a new-generation high-speed, high-torque and high-power twin screw extruder realizing technological promotion based on the existing product by drawing experience from the advanced manufacturing technology in China. Screw elements install like building blocks, piece by piece. Differ design can be for different material.
The advantages of this machine
1. Highly efficent: the machine is automatic and with less power consumption.
2. Special screw design: We will design the screw up to customer different material and the material of screw and barrel can be 38CrMoAL or bimetallic.
3. This machine can carry out ideal viscosity of PET without complicated precystallization dryer system. Only a bit IV will be reduced. It can improve IV in the condition of adding some suitable additive.
5. The machine wih long life.

Single screw feeder, feed the PET flakes into the extruder equally and smoothly.
Vacuum degassing on the extruder, you can put one natrual degassing and one vacuum degassing, or you can put two vacuum degassing.
Screen changer for the PET material, its better to use round screen.The material come out from the die(pull trap like noodles pelletizing way, PET must use this pelletizing way. And the its need good vacuum, like roots pump, then the pellets will be much better)
Materil come out from the die
Cooling for the screw( water controlled by electric valves)
Screw elements of the machine
Gale(dry the material)Pelletizer(cutter the strap into pellets)
Raw material and final pellets of the machine
