Single Screw Extruder and Recycling Pelletizing System for Pet

The ACS series compacting and pelletizing system combines function of crushing, compacting, plasticization and pelletizing to one step, applied in the plastics recycling and pelletizing process. ACS system is a reliable and efficiency solution for PP/PE/PET/PVC films, raffias, filaments, PP woven/non woven bags and EPE/EPS/XPS foaming materials re-pelletizing.

Final productions produced by ACS system are in the form of pellets/ granules, can directly put into the production line for film blowing, pipe extrusion and plastics injection, etc.

Working steps of ACS compacting and pelletizing system
 
 
1. Feeding: as standard design, plastic scraps such as film, filament, raffias conveyed into the compacting room through belt conveyor; to handle rolls' scraps, roll hauling off device is an optional feeding method. Motor drives of conveyor belt and hauling device cooperate with ABB inverter. Feeding speed of conveyor belt or roll hauling off is fully automatic based on how full the compactor's room is. Metal detector can be combined with belt conveyor, and can interlock with control system, to warn and stop the system, in case that metal is found in feeding section.

2. Crushing and compacting: the rotatory blades of compactor will cut up incoming scraps. Frictional heating which caused by high speed rotatory blades will heat and let scraps shrinking just below their agglomerating point. Optimal designed guide structure compacts the material and directs it into extruder screw. Crushes, dries and compacts the material which enables a fast and stable feeding from the compactor directly into the extruder.


3. Sliding gate: installed between compactor outlet and feeding barrel side inlet;to control the materials duration time in the compactor by the open size of the sliding gate and adjust compacted material feeding capacity.




4. Plasticization and degassing: A specialized single screw extruder applied to gently melt the pre-compacted material. The plastic scraps will be well melted, plasticized in a 32 to 34D processing section. With double-zone vacuum degassing system combined with roots pump unit, limit vacuum degassing pressure can be guaranteed reaching -0.1MPa, to remove the volatiles from PET melts maximumly through degassing unit, so as to guarantee tiny IV value reducing.
 
                                                  
5. Melt filtration: a regular pillar type screen changer is installed on head of extruder to present significant filtration performance. The requirements on the filter technology depend heavily on the quality of the input material as well as the planned use of granules. 

6. Pelletizing:
Strands pelletizing unit is the typical PET pelletizing method, the strands which come out from extruder's die section, will be manually hauled into the water trough to cool, then, water removed through the air knife device, cut by the rotary blades of pelletizer and form the granules/chips.
 

 Main technical parameter:

 
ACERETECH: professional equipment manufacture of PET film/flakes/filament re-pelletizing, can provide PET film/flakes/filament re-pelletizing completed solution
 
Concentration makes profession: ACERETECH only focus on studying of waste plastics re-pelletizing technology over the years, has accumulated a wealth of experience on both waste plastics recycling process and related machinery manufacturing ;
 
Trans-industry coordinating : thanks to the coordinate with compounding technology, applying the feature of high volatilization performance from twin screw extruder into PET re-pro process, to assure high efficient degassing performance;
 
IV value reduced within 0.03 - 0.06 ( test based on clean and dried PET flakes)
 
Advantages of ACS compacting and pelletizing system

1.Combine crushing, compacting and pelletizing steps in one system, less-labor cost;

2.Higher efficiency feeding, suitable to film, filament, raffia, foaming materials;

3.Higher output and lower energy consumption.

Why choose us
