How exactly is a granulator knife sharpened?

  • Professional knife sharpening is a process that involves various steps.
  • Precise knife sharpening typically begins with cleaning and removing any residue, to facilitate a high-quality sharpening.
  • The knives are then carefully measured and sorted to make sure that the least amount of knife material is removed. This ensures the tightest tolerances throughout the set of blades.
  • To properly sharpen granulator knives, the knife is held in place and precisely rotated to match the exact angle requirements needed to meet the tolerances of the granulator machine.
  • As the knife is sharpened, it is flooded with coolant to decrease heat and eliminate the risk of changing the hardness level of the material. Knife edges within a set are all ground simultaneously to a specific width to ensure optimized gap setting.

Professional blade sharpening

Regular professional sharpening of a granulator knife significantly improves the performance of your granulator. On average, a granulator knife can be sharpened at least 10 times before reaching the end of their life. Every time, we take off only the damaged part of your granulator knife protecting the working life of your blades.

At Fernite, we work within strict tolerances to deliver a sharpened knife that is like new.
