PET Bottle Flakes Twin Screw Extruder Recycling Granulating Line
Production process & Machine function:
Screw feeder → Parrallel Twin Screw Extruder → Non-stop hydraulic
screen filter changer → Water cooling tank→ Strand cutting → Blower
→ Storage hopper → Electric control panel
1. Screw feeder: the first step of the pelletizing recycling machine,
PET plastic flakes/scraps conveyed into the hopper through screw,
the screw connect sensor to detect the material in hopper, once the
flakes are full in hopper, the screw will stop; and once empty, the
screw feeder will begin working.
2. Extruder: to plasticization and degassing, a specialized single
screw extruder applied to melt the pre-compacted material. The
plastic scraps will well melted, plasticized in the first stage
extruder, and the plastic will be extrude by the second stage
extruder. With double-zone vacuum degassing system, volatiles such
as low molecular and moisture will be removed efficiency,
especially suitable to heavy printed film and material with some
3. Non-stop hydraulic screen filter changer: double stage filtering,
fore filtering in the first extruder, and fine filtering in the
second extruder, to reduce the frequency of filtering sieves
changing. The requirements on the filter technology depend heavily
on the quality of the input material as well as the planned use of
4. Water cooling: made of 304 stainless steel, 4 meters length that
fill with water, too cooling the melted plastic.
5. Cutting pelletizing: supplied with speed steel and hard alloy
steel cutting blades for reliable performance. Compact structure
allows less maintenance.
Introduction of Plastic recycling pelletizing line:
1. Twin screw extruder recycling & pelletizing system are applied
to the waste materials, which needs high processing performance of
melting, volatilization, filtering etc., mainly works for the job
of PET scraps recycling and re-pelletizing.
2. To slowing down IV reducing during PET flakes/scraps recycling,
not only impurities, such as PVC content, moisture, etc., but also
precise recycling system and reliable equipment configurations are
necessary to put in the solution.
3. PET plastic pelletizing machine with international advanced
recycling technology and combined with the actual application
condition. This PET plastic pelletizing machine is design
specializes for recycling the recycled washed plastic PET plastic
flakes/scraps, such as Cola plastic bottle flakes/scraps, purified
water bottle flakes/scraps, PET sheet flakes/scraps, PET drinking
bottle flakes/scraps etc.
4. After processing techniques such as feeding, heating, melt,
cooling, drying, cutting etc., the final products are PET plastic
pellets/granules that can be to produce new PET plastic products.
Features of Pet bottle flakes granulating line:
-The screw is made of high tool steel 38 CrMoALA or W6Mo5Cr4V2.
Special screw combination Euro-style rectangle barrel, reflux
refrigeration channel optimized and disposed, which makes
temperature difference in D areas smaller.
-Innovated design of heater-tightened style insures high efficiency
of heat transfer and high longevity of heater.
-The material is used high quality nitride steel, corrosion proof or
antifriction with corresponding processed special designed two sets
-New-style project of parallel three-axis driving makes the convex
axis, convey Chain, decelerate and torque get together, which keep
it compact, and the key bearings are imported soakage and spraying
lubrication integrate smoothly technics, strengthening of tooth
face, so they can ensure high torque, high precision and low noise
The selected material of drive components is dainty, including
super intention alloy, cementiteing steel, cementiting and
-Operation is simple,Very low labor request.
-Automatic constant temperature control.
-Stable running, higher output and lower energy consumption.
-Configuration based on client requirement and material, and give
