Single Screw Extruder for Plastic Regrinds or Flakes

Applicable to:
Regrinds crushed or flakes of PE/PP/ABS/PS/HIPS/PC etc.
 
Description:
The ADS180/200 single screw extruder and pelletizing system applied in the re-pelletizing job which consists of two sets of single screw extruder, in case that recycles are with heavy dirty or required more output,so as to get the final granules or pellets we need.
 
Process: Lumps or thick flakes after crushed, conveyed into the single screw extruder by screw loader, then, compress, plasticize in the extruder and removed the volatiles and moisture by the vacuum system, after filtering through the filtration system, to pelletize into granules. Depending on different screw diameters of single screw, the typical capacity can cover from 650kg/h to 800kg/h.
 
Features of two-stage re-pelletizing system:
1. segmented filtering principle, fore filtering in the first extruder, and fine filtering in the second extruder, to deduce the frequency of filtering sieves changing
2. thanks to separated filtering system in two-stage extruder, system can realize steady extrusion job
3. has one more volatilization between first and second extruder
4.second stage's extruder can present low temperature extrusion, which can guarantee the final production's quality


Specification: 
Main technical data:
Main parts of ADS180/200 extruder & pelletizing system
1. Feeding: as standard design, lumps or thick flakes after crushed conveyed into the extruder through screw loader. Motor drives of loading and hauling device cooperate with ABB inverter. Feeding speed of screw loader is fully automatic. 
2. Plasticization and degassing: A specialized single screw extruder applied to gently melt the material. The plastic scraps will be well melted, plasticized in a 32D processing section. With double-zone vacuum degassing system, volatiles such as low molecular and moisture will be removed efficiency, especially suitable to crushed regrinds or flakes with some water content.
 3. Melt filtration: a regular single-plate/ piston double-station screen changer or non-stop double-plate/ piston four-station can be 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.
 4. Pelletizing: die-face water ring pelletizing system set as the standard granulating method in ADS system. Self-adjusting pelletizing head for the best granulate quality and long uptime thanks to consistently correct blades pressure. RPM of rotatory blades is automatic based on melt extruding pressure. Advanced dewatering vibration sieve combining with horizontal-type centrifugal dewatering present high performance dried pellets. 
In addition:
We provide the machine of good quality (Strict quality control ,good reputation in the market) and the good service, we deliver the products on time.
