Description for Plastic recycling granulator of SJ Model Pelletizing Extruder


A. Features of crushed flake granulator:

  • Higher output and  lower consumption (0.27kwh/kg to 0.35kwh/kg)
  • To compare with other supplier,  20%  output more than our first -generation products
  • To compare other suppliers, 15% less than consumption our first -generation products
  • 2 labors operating the whole line


B. Applications of plastic bucket, basin, barrel, milk bottle, chemical bucket, container pelletizing/granulating extruder: 


Applicable plastic materials: PE, HDPE, LDPE,PP, etc

Material shapes:  rigid flakes, crushed flake and washed flake

Note: depending on different material properties, various downstream equipment are needed.


C. How it works


①Screw charger uploading the material by timer

②Feeder and extruder is controller by frequency inverter,

③Different L/D for different material  

④Nature degassing, vacuum degassing adopting for moisture

⑤ Water ring die face cutting for perfect pellets shape

How to choose pelletizing way ?

A. Water ring pelletizing ( vertical water ring pelletizing system, horizontal water ring pelletizing system )

To compare strand pelletizing, water ring pelletizing system can saves labor work.

Cylinder compress blade ensure the output pellets at balance.

B. Strand pelletizing 

PP MFI >10 

output strip get cooled in water tank, and then get cut by pelletizer

C. Underwater pelletizing 

Mainly used high melt index materials.

Cutting and cooling together with output round pellets
