Parallel Twin-Screw PET Flakes/Scraps Plastic Pelletizing Machine

Description of PET plastic pelletizing machine: 

Parallel twin screw extruder recycling and 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.

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.

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.

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:

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 of vacuum.

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 grinding.

Working Flow of Parallel twin-screw PET plastic pelletizing machine:
Screw feeder → Efficient extruder → Non-stop hydraulic screen filter changer → Water cooling → 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 water content.

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 granules.

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.
