Double Stage Plastic Film Granulating Line With Compactor

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.

Double Stage Plastic Film Granulating Line 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.

Double Stage Plastic Film Granulating Line Components:

Conveyor (With metal detector) Agglomerator
Conveyor (with metal detector)
Metal detectors can be combined with belt conveyors, and can interlock with the control system, to warn and stop the system, in case that metal is found in feeding.
Agglomerator
Agglomerator combines pre-heating, pre-dry and size reduction to ensure a fast and stable feeding process.
First Stage Screw Extruder 1# Full Auto Hydraulic Screen Changer With Double Working Position
First Stage Screw Extruder
Our unique design single screw extruder gently plasticizes and homogenizes the materials. Our extruder has great anti-corrosion resistant, wear resistant and long life time.
1# Full Auto Hydraulic Screen Changer With Double Working Position
Filter material impurity, to make production more stable.
Second Stage Screw Extruder 2# Full Auto Hydraulic Screen Changer With Double Working Position
Second Stage Screw Extruder
usually adopts a small L/D extruder, further plasticizing the material and filter contamination which can achieve stable extrusion.
2# Full Auto Hydraulic Screen Changer With Double Working Position
Long screen lifetime, lower screen change frequency: Long filter lifetime owing to large filter areas. Easy to use and none-stop type: easy and quick screen change and do not need to stop the running machine.
