Frequently Asked Questions from our Customers

What is the difference between shredder blades and granulator blades?

Although both shredder blades and granulator blades are used in plastics recycling and size-reduction systems, they are designed for different stages of the recycling process and perform very different cutting functions.

Shredder blades are designed for primary size reduction.
  • tear and rip material apart
  • handle large bulky feedstock
  • prioritise torque and durability
Granulator blades are designed for secondary size reduction and precision cutting.

  • cut material precisely
  • refine material into uniform granules
  • prioritise cut quality and consistency
Both blade types are commonly manufactured from wear-resistant steels. However, shredder blades often prioritise toughness, while granulator blades prioritise edge retention and cutting precision.

What machine brands are shredder blades compatible with?

Our shredder blades are compatable with various brands: Vecoplan, Weima, Zerma, Untha, Lindner, SSI shredder cutters.
