How to Choose the Right Plastic Pelletizer System

The key factors to consider when choosing a plastic pelletizer system include material compatibility, production capacity, energy efficiency, space and installation, and maintenance requirements. Most importantly, choosing the excellent pre-processing shredding and crushing equipment can make the pelletizer system more efficient. Below is a detailed introduction of GENOX recycling system.



Pre-Processing: The Foundation of Effective Pelletizing

The shredding and cleaning systems are the front-end core of plastic recycling, and their efficient pretreatment directly affects the stability and particle quality of the pelletizer system. The pre-processing steps and key equipment include:

  • 1、Shredding: Reduces bulk materials into smaller, uniform pieces. Film type materials are opened up to enable effective cleaning and washing.

    GENOX YS Series - Pre-Shredder: High-torque, low-speed, low dust and noise operation machine for films, rigid plastics, and bulky waste.

    GENOX V Series - Single Shaft Shredder: Small-medium size reduction machine suitable for processing a wide range of materials to a uniform particle size.

  • 2、Crushing/Grinding: Further reduces particle size for consistent feeding.
    GENOX GC Series - Granulator: High speed granulation machine for processing a multitude of materials including plastics, rubber, fibers, copper cable and light non-ferrous metals amongst others.

  • 3、Washing & Drying: Essential for contaminated materials (e.g., post-consumer films).
    Pre-washing system removes a large percentage of abrasive materials (sand, grit etc.) to protect the rest of the system.

    High speed washing system is optimized according to the specific material type liberates and separates contamination from film flakes.

    Under water force-washing paddles in our washing tanks maximize the washing efficiency.Our drag chain discharge device regulates the material discharge speed and minimizes the water volume sent to the drying process with the product.

    Mechanical (centrifugal and squeezing) and thermal drying systems control the moisture content of the finished product. At < 5% moisture content, the material is suitable for high quality pelletizing.

Selection of Pelletizer System: Meeting Material Requirement

Plastic pelletizing is a thermo-mechanical process in which pre-shredded or pre-treated plastic waste is melted at high temperatures and reformed into uniform, stable, and standardized recycled plastic granules—typically cylindrical or spherical in shape.

The type of plastic material you are working with significantly influences the choice of pelletizer. Common plastics include:
Polyethylene (PE)
Polypropylene (PP)
Polyvinyl chloride (PVC)
Polystyrene (PS)
Technical plastics (ABS, nylon, etc.)

Each material has different melting points, viscosities and handling requirements. Make sure that the pelletizer you choose is compatible with the specific type of plastic you want to process.

Technical Specifications to Consider

When comparing different pelletizing systems, it is recommended to consider the following technical specifications:

  • Throughput capacity
  • Output diameter (customizable)
  • Rotation speed
  • Temperature range
  • Heating & cooling requirements
  • Operational efficiency
  • Energy saving
  • Lower maintenance cost

Why GENOX Stands Out

Selecting the right supplier is just as important as choosing the right plastic recycling machine. GENOX stands out with:

  • Proven industry experience
  • Leading R&D capabilities
  • The ability to customize solutions
  • Access to testing facilities for your specific materials
  • Reliable after-sales support
