LDPE HDPE BOPP Film Pelletizing Plastic Granulating Machine Description:
Double stage plastic granulating machine is especially good for the raw material which contains 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.

LDPE HDPE BOPP Film Pelletizing Plastic Granulating Machine Components:
| 
|
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 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 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. |
| 
|
Water Ring Pelletizing System Cutting the material into pellet. Water ring pelletizing system set as the standard granulating method. self-adjusting pelletizing head for the best granulate quality and long uptime thanks to consistently correct blades pressure. | Dewatering And Air Sending System Centrifugal dryer to get well-dried final granules. |
 | 
|
Silo Storage the final pellets in a bag. | Electronic Control The whole model adopts frequency conversion control and conforms to international standards such as CE/CSA. |
Detailed description of each item:
1. Conveyor: convey PP PE film or flakes into the 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.
