Product Description
Plastic Pelletizing Machine

PP PE HDPE LDPE Plastic Pelletizing Machine Waste Plastic Granulator Recycling Machine.

We provide a dedicated single screw pelletizing line for soft plastic film. The system integrates compacting feeding, main screw plasticizing, screen changer filtration, second stage plasticizing, water-ring pelletizing, dewatering, and collection. Output ranges from 200kg/hr up to 1000kg/hr.

⚙️ Applications: Suitable for specialized plastic recycling plants, offering low energy consumption, stable output, and long service life.
  • Applicable materials: PE, HDPE, LDPE, PP, BOPP, PET, PA/Nylon, etc.
  • Material shapes: Film, bag, fiber, rope scrap.
  • Material types: Rolls, loose, bundled.
  • Source: Offcuts, industrial defect materials, washed materials, and printed materials.

The final pellets can be directly used in production lines for film blowing, tube extrusion, and injection molding.

Process Flow
Single Stage Pelletizing Line:
Belt conveyor → Metal detector → Film Agglomerator/Compactor → Single screw extruder → Hydraulic filter changer → Die head → Water ring cutting → Dewatering machine → Vibrator → Air dryer Blowing system → Storage hopper.
Double Stage Pelletizing Line:
Belt conveyor → Metal detector → Film Agglomerator/Compactor → 1# Single screw extruder → 1# Hydraulic filter changer → 2# Single screw extruder → 2# Hydraulic filter changer → Die head → Water ring cutting → Dewatering machine → Vibrator → Air dryer Blowing system → Storage hopper.

Frequently Asked Questions
What types of plastic materials can this machine process?
The pelletizing line is ideal for PE, HDPE, LDPE, PP, BOPP, and PET in various forms such as films, bags, fibers, and ropes.
What is the humidity level of the final pellets?
Thanks to our horizontal dewatering device, the final pellet humidity can be controlled to less than 1%.
How does the machine handle printed or moist materials?
The extruder is equipped with a double-zone vacuum degassing system that efficiently removes volatiles and moisture, making it perfect for heavy printed films.
What are the main electrical components used?
We use world-class components including Siemens or Weg motors, Siemens PLC controllers, ABB or Siemens inverters, and NSK bearings for maximum stability.
Is the machine noisy during operation?
No, our new design includes pipes and silos wrapped with black sound insulation cotton, reducing noise levels significantly from 82dB to 68dB.
What is the production capacity of the ML series?
Depending on the model (from ML85 to ML180), the output ranges from 180kg/h to as high as 1200kg/h for LDPE/LLDPE materials.
