Plastic Pelletizing Lines

Create High-Value, Uniform Plastic Pellets

Our advanced plastic pelletizing lines are the final step in transforming recycled plastic waste into a valuable, consistent, and reusable raw material. We engineer complete systems for compounding, modifying, and pelletizing a wide range of polymers.

Choosing The Right Pelletizing System

The ideal technology depends on your material type, output requirements, and operational preferences. We specialize in two primary, highly efficient systems.

A Water-Strand Pelletizing unit.

Water Strand Pelletizing Line

A classic, robust, and cost-effective method ideal for a wide variety of polymers, especially those sensitive to temperature changes.

  • Process: Molten plastic is extruded into strands, cooled in a water bath, and then cut into pellets by a granulator.
  • Best for: PET, Polystyrene (PS), and highly-filled or reinforced compounds.
  • Advantage: Simple operation, easy to clean, and versatile for lab or large-scale production.

Water-Ring Pelletizing Line

A more automated and compact system that cuts pellets at the die face, ideal for high-volume production of polyolefins.

  • Process: Blades rotate at the die face, cutting pellets which are instantly quenched and transported by a circulating water ring.
  • Best for: PE, PP, and other materials with lower melt viscosity.
  • Advantage: Produces uniform, spherical pellets, requires less floor space, and is highly automated.

Engineered for Ultimate Pellet Quality

Every component is selected to ensure the purity, consistency, and value of your final product.

  • Automatic screen changer for continuous melt filtration.

    Continuous Melt Filtration

    Automatic screen changers remove contaminants without interrupting production, ensuring a pure melt stream.

  • Vertical centrifugal dewatering machine.

    Efficient Dewatering

    A vertical centrifugal dryer rapidly removes surface water from the pellets, preparing them for classification and storage.

  • Vibrating screen for pellet classification.

    Pellet Classification

    A vibrating screen classifies pellets by size, removing oversized or undersized particles for a highly uniform final product.

  • Co-rotating twin-screw extruder for compounding.

    Precision Twin-Screw Extruder

    Provides excellent mixing and dispersion for compounding applications, ensuring homogeneity of additives and fillers.

PP/PE film pelletizer machine, designed for the recycling and pelletizing of polypropylene (PP) and polyethylene (PE) films. This comprehensive setup features several key components arranged in a linear format for efficient processing: 1. **Feeding System:** At the far left, a large vertical hopper equipped with a staircase for access, where raw plastic film materials are introduced into the system. 2. **Extrusion Unit:** The central part of the image shows a long, horizontal extruder, typically the heart of the pelletizing process where the plastic films are melted and extruded. 3. **Pelletizing Section:** Following the extruder, the melted plastic is cut into pellets, a process likely taking place in the machinery shown towards the right of the image. 4. **Cooling and Collection:** The pellets are then cooled and collected, with additional machinery and hoppers indicated towards the far right to handle the final stages of the process. The system is depicted in a clean and precise rendering, highlighting its modular design and the integration of each phase of the pelletizing process. This setup is essential for recycling facilities focused on processing and repurposing plastic waste into a usable form.

Cutter Compactor Recycling Granulating Line

Recycling lightweight, fluffy materials like plastic film and fibers presents a unique challenge for standard granulators. Our Cutter Compactor Recycling Granulating Line is the all-in-one solution designed specifically for this task. The integrated cutter compactor unit shreds, dries, and densifies the material before it even enters the extruder, ensuring a stable, high-volume feed and preventing common issues like bridging. This streamlined process transforms a wide range of plastic scraps, from PE films to PP woven bags, into uniform, high-quality pellets, making it a highly efficient and cost-effective investment for your recycling operation.
