waste PET bottles flakes scraps granulating pelleting line/pelletizing line with high capacity, PET cans and so on. 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.

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.

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)

Cooling for the screw( water controlled by electric valves)

Screw elements of the machine

Vacuum, we can use Roots vacuum or Bipolar pump.
