HD LLDPE Flakes Extrusion Recycle Granultor Plant

HD LLDPE Flakes Extrusion Recycle Granultor Plant

Device overview

Mother and baby extrusion granulator with Single Screw, it has two cascade extruder and mainly used for processing rigid crushed HDPE LDPE PP flakes, regrind HDPE LLDPE flakes such as hollow container, buckets, deskes, chairs, milk bottles, baskets and car parts and so on.

If the material is too dirty, we can use a washing machine to wash the material first, and the washing machine include crusher,washing and dryer, so that the clean plastic flakes need to be granuated by extruders. Then the finally hese granules can be for further production and processing of plastics into finished products, which can be by blowing, injection and calendering. The total granulation line combines quantitative feeding, high efficiency double extruder,different types of filter and different types of pelletizer by modular design. All the machines are customized. 

Of course, we have single stage extruder, double stage extruder for choosing. According to different material and different requirements, each machine can be specilized desigined.

Machine details

single screw extuder feeder.jpg

Single screw feeder

Single screw feeder can feed the raw material into extruder equally and stable. There is sensor in it, when it is full, the loader will stop by itself, and when it is empty, the loader will restart. Meanwhile, there is sight glass to see the material in the hopper.

Extruder with vacuum degassing

There is vacuum degassing on the extruder to vent the gas in the material, so that there is no bubble in the final pellets. 

extruder Interstage transition.jpg

Interstage transition

It is a Multidrilled head that the material go from the first extruder into the second extruder through this interstage transition. Natural degassing can let more gas humidity out, we also can install a second degassing here. With two stage extruder, the material can go stable and the capacity of the machine will be confirmed.

Granules vibration

Two layer screen vibration can seperator the pellets. With its select, customer can keep good granules in way, and packed them to sell. All screen will be made by stainsless 304

single extrusion first stage.jpg

First extruder

Each screw is special designed accordingto its material, inorder to plastify, heating different material in good way.so that the screw and barrel can have the long life. Different kinds of heaters will be disigned in right way. Fan out side to cool the material.
