How to select a most suitable plastic granulator?

2025-10-23

Choosing the most suitable and right plastic recycling granulator depends heavily on the specific characteristics of your plastic waste and your production goals. To make the best choice, follow a systematic process:

1. Analyze Your Waste Material in Detail: Collect all the information, such like plastic type and Properities (PP, PE, PS, ABS, PVC, PPR. BOPP, PET……),waste form & size, source& contamination, Required output(kg/h) Providing photos of your waste material can be very helpful for suppliers to give accurate recommendations.
2. Define Your Final Pellet Specifications: Determine the required size, shape, and quality (e.g., freedom from bubbles or unmelted material) of the recycled pellets, as this influences the choice of pelletizing system.
3. Evaluate Key Machine Components:
   · Screw Design: A single-screw granulator is often sufficient for simple, uniform materials. A twin-screw or double stage granulator offers better mixing, degassing, and processing stability for contaminated or complex materials.
   · Degassing System: Essential for removing moisture and volatiles (often from inks) from the melt. 
   · Filtration System: A automatic screen changer is crucial for filtering out solid impurities from contaminated plastics to ensure pellet purity.
4. Plan for the Long Term: Consider your business's potential for expansion. Investing in a machine with higher capacity may be more economical than buying a second one later.
5. Request Professional Consultation and Testing: Reputable suppliers can provide detailed questionnaires and often conduct tests with your actual material to ensure the machine meets your expectations.
