Choosing the correct granulator blade

In order to choose the most efficient, cost-effective knife, various questions must be answered. These together with our experience will enable us to make an assessment of your requirements and put forward the best recommendations.

  • What material is being processed? hard, soft, large or small section?
  • Is there likely to be a risk of contamination?
  • How abrasive is the material?
  • Does the knife operate in a corrosive environment?
  • Cost. A large section knife is generally cheaper if a tipped knife is used, whereas a knife of small sectional area is invariably cheaper if made from heat treated alloy steel.
  • What issues are you experiencing with your current knife?
D2 Tool Steel versus Tipped Blades, which is best for you?

Standard D2 Tool Steel

Machine knives have traditionally been made from heat treated alloy steels which can provide extreme hardness, good abrasion resistance and can be ground to very acute angles.
This is the most common type of blade used in granulation systems. However, if you are having problems such as large chips, blades becoming dull quickly and breakages, then it’s  probably time to consider a tipped blade.

When to choose a toughened, tipped or superior tipped blade.

An important factor to remember, is that a damaged tipped knife can be repaired, provided that there is sufficient grinding life left in the knife. Our tips are manufactured into the blade, subsequently forming a complete mechanical and metallurgical bond. 

Considerable cost savings arise using this type of blade, especially ones with a large cross-sectional area. The special advantage of these knives is their shatterproof quality which prevents damage to the granulator machine. This is because a tipped blade will twist rather than shatter like a solid tool steel blade. Being shatterproof is particularly important when the material being processed may be contaminated by foreign matter. 

Fernite tough tipped blades are ideal where there is a risk of contamination, or where D2 blades are prone to suffering larger chips. Our toughened blades retain their sharpness for longer and any chips will be smaller. So, this means that any damage sustained can be repaired by sharpening the blade. Whilst sharpening the blade , we’re able to remove less material extending both the efficiency and the working life of the blade.

Our superior tipped blades are ideal for heavy duty cutting and where the material processed is operated at an elevated temperature.
