Waste LDPE HDPE Crushing Extrusion Pelleting Recycling Machine

Waste LDPE HDPE Crushing Extrusion Pelleting Recycling Machine

Device overview

Single Screw cascade extruder with water-ring pelletizer system is mainly used for processing rigid flakes, crushed flakes, regrind flakes, hollow container, buckets, Such as deskes, chairs, milk bottles, baskets car battery boxes and car parts. 


After crushed,washed and dried, then the plastic flakes need to be granuated by extruders. Finally hese granules can be further processed into various plastics products by blowing, injection and calendering. The total granulation line combines quantitative feeding, high efficiency extruder,different types of filter and different types of pelletizer by modular design.

Machine details

screw loader.jpg

Rotary charger

As a special design, send the crushed rigid flakes material into the feeder on the extruder by screw. The equipment use inverter to control the speed. It can control together with the Feeder, If the material in the feeder is full, then the rotary charger will stop by itself.

Feeder

Feeder the material into the extruder evenly and stably. If people don’t use feeder, the extruder maybe choked in the mouth. And it can check when the hopper is full, then the loader will stop by itself.


extrusion degassing.jpg

Degassing on extruder

Usually we will put two degassing on the extruder, one is natural and one is vacuum, we also can use one vaumm pump control two vacuum degassing. Different material needs different kinds of degassing.

extruder fan.jpg

Extruder fan

There is heater on the extruder, then it need to be cold by fan when the temperature is too high. So the material can be in the good conditation.  Double mounth fan can cool the material well.

water-ring cooling pelletizer.jpg

Water cooling pelletizer

Material come from hydraulic screen changer will filter out and remove the impurities inside of the material. Then the cutter will cut the material into pellets. According to different kinds of material, we will design the different kinds of pelletizing way, such as water cooling, fan cooling.



pelletizer die.jpg

Die head

here is die head in water-ring pelletizing system. According to different raw material, the dies are also different. And the size and numbers of the hole in the die can be designed as requirement. Such as PP and PE die head.

Extrusion machine

The extrusion machine outlook also can be designed. We also can use a cover for the machine. But this way just difficult to change the heater.
