We manufacture fly and static Granulator Knives for all types and sizes of granulators. Recycling is one of the most difficult cutting application, because of processing various materials. Subsequently, this might cause premature wear and even chipping of granulator knives. Therefore, during our manufacturing process we make every knife

  • with different hardness and bevel configuration (keen edge, reverse bevel, high shear, hook fly) to match granulator knives performance with each application.
  • using enhanced heat treatments to reduce corrosion and plastic deformation.
  • applying special coatings to ensure rust and abrasion resistance of knives.
  • matching cutting edge geometry with your application to resolve wear or breakage issues.

Sometimes, our customers ask us ‘ What are the main problems of a granulation process? ‘ However, it is not a simple answer. It is a combination of a granulator type, size of a cutting chamber, characteristics of your knife, and quality of plastic that affect the outcome granules. Therefore, granulating different materials requires Granulator Knives with different parameters. We recommend the correct steel grade for every specific application. Above all, if you require, our technicians can give an advise on rotor and stationary granulator blade and knife models geometry, various heat treatments, and coatings.

In addition, we provide a comprehensive sharpening and grinding.  Please follow the link if you would like to get more information about our granulator blade sharpening services.
