High-Quality Granulator Blades for the Plastic Recycling Solutions
High-Performance Granulator Blades for Industrial Applications
Plastic Granulator Blades are the crucial component of granulator machines. They significantly impact the efficiency of the granulation process.
Problems that might arise whilst using Granulator Machines
Material tearing instead of cutting
Uneven or poor quality granulated granules
Noticeable decrease in throughput
Excess noise
These problems usually mean that sharpening the granulator blades is required to maintain optimal performance. We offer a professional granulator blade sharpening service, with a regular pick up/collection service throughout the UK.

But remember, blades can only be sharpened a limited number of times, usually 8 – 10 times, depending on how much material is removed per operation. Once the blade reaches the limit, the blade will need to be replaced.
Don’t wait when it is too late; make arrangements in advance to replace the blade.
Bespoke Granulator Blades for your specific application
Fernite supplies precision-engineered granulator blades designed for optimal performance in plastic recycling and size reduction operations. Our blades deliver exceptional cutting efficiency, extended service life, and consistent particle size reduction across various materials and applications.
Types of Granulator Blades We Supply
Rotor Blades (Cutting Blades)
The primary cutting elements are mounted on the rotating shaft of the granulator. Available in various configurations, including V-shaped, double-angled, and helical designs.
Stator Blades (Bed Knives)
Stationary counter-blades that work in conjunction with rotor blades to create the scissor-cutting action. Our stator blades are manufactured from hardened steel with optimized clearance specifications to ensure clean cuts and minimize plastic melting during size reduction.
Screen Perforated Blades
Specialized blades designed for granulators equipped with screening systems. These ensure consistent output particle size by controlling material discharge. Available in various hole sizes to meet your specific regrind specifications.
A wide range of Granulator Blades in stock
We manufacture plastic granulator blades that are compatible with many granulation systems. If your machine is not on this list, we are still able to manufacture to your drawing.
We Manufacture Blades for All Stages of The Plastic Recycling Process

- ▸Does the knife operate in a corrosive environment?
- ▸What issues are you experiencing with your current knife?
Frequently Asked Questions from our Customers
Choosing the right blade material can dramatically impact operational efficiency and cost-effectiveness. In heavy-duty applications, these blades provide a shatterproof quality and enhanced heat resistance.
The advanced tip technology ensures sustained performance across demanding operations, significantly reducing blade replacement frequency and minimizing production interruptions. Please get more information about Granulator Tipped Blades.
The most destructive cause of premature blade failure is metal contamination. Beyond metal, abrasive materials present another serious challenge. Glass fiber reinforced plastics, mineral-filled compounds, and dirt-contaminated post-consumer waste act like sandpaper against blade edges. Each pass gradually dulls the cutting edge, reducing efficiency and increasing the load on your entire system. What starts as slightly reduced sharpness quickly accelerates into a performance problem that affects throughput and energy consumption.
The next reasons are installation, maintenance, and the mix of old and new granulator blades, which creates imbalanced forces and poor performance. Inadequate performance of the rotor and screens might also create imbalanced forces and contribute to the overall vibration.
Other factors as different plastics behaving differently, having proper blade clearances can wear blades. The key is recognizing that blade wear isn’t just about the blades themselves—it’s about the entire system working together properly.
