Twin Screw Extruder Pet Bottles Flakes Scraps Recycled Granulating Pelleting Line

Twin Screw Extruder Pet Bottles Flakes Scraps Recycled Granulating Pelleting Line


twin screw extruder  PET bottles flakes scraps recycled granulating pelleting line, PET cans and so on. The device with High-torque twin-screw extruding screw device, this  is a new-era high-pace, substantial-torque and substantial-electrical power twin screw extruder recognizing technological promotion based on the present merchandise by drawing experience from the innovative production technological innovation in China.


The benefits of this machine
1. Very efficent: the device is automated and with considerably less electricity use.
2. Particular screw layout: We will style the screw up to client different materials and the materials of screw and barrel can be 38CrMoAL or bimetallic.
three. This equipment can have out ideal viscosity of PET CZPT complex precystallization dryer method. Only a little bit IV will be decreased. It can boost IV in the problem of introducing some ideal additive.
five. The equipment wih extended life.
