Two Stage Pelletizing Machine PP / PE Film Recycling Line ML Pelletizing Machine

Product Specification

PP PE films recycling machine ML two stage pelletizing machine ML160 180 600kg-800kg per hour

01. Better plasticizing effect

The second-stage single screw extruder provides a more uniform plasticizing effect, ensuring that the hard plastic is fully melted.

02. High-purity particles
Through two-stage processing, impurities can be removed more effectively and the purity of the final plastic particles can be improved.

03. Strong adaptability
A variety of hard plastics can be recycled, such as PE/PP/ABS/PS/HIPS/PC, etc., with a wide range of applications

04. Stable output
The two-stage system ensures the stability of the production process and can continuously output high-quality plastic particles.

05. Two-stage design
Although it is a two-stage design, it has a high degree of automation, simplified operation procedures, and reduced operation difficulty.

06. Extend equipment life
Pretreatment reduces the wear of the hard plastic on the extruder and extends the service life of the equipment.

Barrel
Due to the extra-long aspect ratio, the single-stage extruder in the production line can be used as a two-stage extruder. After the middle double-piston screen filter, a filter can be added at the end. The double filtration standard can improve the quality and performance of the final product particles.

Single screw extruder
Our unique design single screw extruder gently plasticizes and homogenizes the material. Our bimetallic extruder has good corrosion resistance, wear resistance and long life.

Two-stage screw extruder
It consists of two single screw extruders, suitable for printing ink heavy, high moisture content, poor fluidity, temperature sensitive, high impurity content, double filtration system, multiple exhaust and other higher requirements, longer process materials.

Models

According to the raw material condition, we could redesign the pelletizing line.

1.Shredder or crusher

• If you recycle the raw material is large rolls, you might need one shredder or crusher to shred it into small pieces, then go to the cutter compactor.

2.Cutter compactor type

• In the cutter compactor there are some rotary blades fixed on the middle rotary plate and fixed blades mounted on the walls of the cutter compactor.
• For normal PP PE films single plate type is enough. For the PET raw materials we tested the two plates will be good.

3.Degassing system

• Non degassing system suitable for the clean films
• Natual degassing system suitable for the normal films
• Vacuum degassing system suitable for the materials washed and need to remove some the ink and gas.

4.Screen changer system

• Several options depending on the raw material condition and customer prefer
• Plate type: easy to option, normal filtering space
• Piston type round filter: Suitable for clean materials
• Piston type large filtering space: Suitable for much dirty materials, such as the washed PP PE films. Less change filter frequency, save labour work, increase the capacity. To change the filter will be a little longer than the plate type and piston type. While you are familiar with it, it will be quick.
• Laser filter or non mesh filter: It is the automatically no need to change the filters or screens. It is with a filter plate or two plates inside with two rotary blades to rotate to scrap the dirty. The screen mesh could be 40mesh, 60 mesh, 80 mesh.

5.Pelletizing system

According to the raw material characteristics, we have the below several options:

• Watering pelletizing system. The horizontal watering pelletizing suitable for the PE films, and vertical watering pelletizing system will be good for the PP type.
• Dry strand pelletizing system suitable for most raw material, including the engineering polymer, such as PP(film grade or the blow and injection grade) PE(film grade or the blow and injection grade), ABS, PC, etc
• Wet (undewater)strand pelletizing system is suitable for the PET, such as the PET bottle flakes, PET fiber, BOPET films etc.
• Underwater pelletizing is suitable for the PP rigid PE rigid or the PBAT material for customer have special requirement.

6. After the different pelletizing system we will offer the dewatering system and vibration and transmission and silo for the packing.

Our company has been in the plastic recycling field for more than 18 years with much experience. We could offer the best solution for customers from all over the world to finish the project. We have mature aftersale service and promption replying technical service to offer to our customers.
