Double stage pelletizing line is especially good for the raw material which contain high moisture, high impurities.
The first stage extruder adopts exhaust type barrel screw, which can effectively de-gassing and eliminate the moisture and contamination;
And the second extruder usually adopts small L/D extruder, further plasticizing the material and filter contamination which can achieve stable extrusion.

Process flow: 

Conveying feeding→ Metal detector →Film Agglomerator /Compactor →1# Degassing  screw extruder →1# Hydraulic filer exchanger→2# screw extruder →2# Hydraulic filer exchanger→ Mould head →water ring cutting →Dewatering machine→ Air dryer Blowing system→ Storage hopper→ Finished product packing.


Detailed description of each items:  
1. Conveyor: convey PP PE film or flakes into compactor.
2. PE film Agglomerator /Compactor: crushing and compress film, and feed compressed film into extruder forced, to make the production capacity high and stable.
3. 1# Extruding system: plasticizing material and exhausting gas.
4. 1# High speed Net exchanging system: filter material impurity, to make production more stable.
5. 2# Extruding system: plasticizing material.
6. 2# High speed Net exchanging system and Die-head: Second filter material impurity, to make production more stable.
7. water ring pelletizing machine: cutting pellets in water.
8. Water tank: cooling pellets.
9. Dewater machine: make pellets dry.
10. Vibration sieve: remove bad pellet and keep good pellet.
11. Air Blower: convey good pellets into silo.
12: Storage silo: keep pellet.
