Frequently Asked Questions
What are granulator knives used for in plastic recycling?
Granulator knives are used to cut and reduce plastic scrap, runners, bottles, films, and other plastic waste into smaller, reusable granules for further processing and recycling.
How often do granulator knives need sharpening?
The sharpening frequency depends on the type of plastic being processed, production volume, and contamination levels. Regular maintenance helps maintain clean cuts and consistent granule size.
Can KKA – Kolkata Knives America manufacture replacement granulator knives?
Yes, KKA manufactures OEM and replacement granulator knives for a wide range of plastic recycling systems based on drawings, machine models, or sample blades.
What materials are commonly used for granulator knives?
Granulator knives are typically manufactured from high-grade tool steels such as D2, A8, and other wear-resistant alloys to provide longer edge life and reliable cutting performance.
Why is knife clearance important in granulator systems?
Proper knife clearance helps improve cutting efficiency, reduce dust generation, lower energy consumption, and prevent unnecessary wear on both rotating and stationary knives.
What causes premature wear in plastic granulator knives?
Premature wear can result from contaminated materials, incorrect knife settings, improper sharpening, metal contamination, or running dull blades for extended periods.
