Can you manufacture granulator blades from a custom drawing or sample?

The answer is yes, we can. If you have a drawing or even only planning your Granulator Blades we can manufacture it for you. If you are looking for a CNC manufacturer of Granulator Blades and Knives please email or phone us to discuss your requirements.

Can you extend the life of my granulator blades?

Fernite offer standard blades made from high quality European Tool steel. To further improve blade life, wear resistance and chip resistance we offer a toughened tip or superior tip. Speak to our sales team if you would like to learn more.

How do you make tungsten carbide tipped granulator blades?

To improve wear resistance of the edge to impact and erosion, we manufacture tungsten carbide tipped Granulator Blades. During the manufacturing process we braze tungsten carbide insert onto the cutting edge of a granulator blade.

Can you identify a granulator blade from a serial number, or do I need to measure the blade?

Fernite has an extensive database of granulator blades that fit many machines locally and abroad. With this large record of various models we can help many customers to identify their blades and manufacture them.

High-Quality Granulator Blades for the Plastic Recycling Solutions

Engineered for durability and optimal performance

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.

We Manufacture Blades for All Stages of The Plastic Recycling Process

Upon your initial enquiry, our technical staff will ask you:

▸
What material is being processed?
▸
How abrasive is the material?
▸
Is there likely to be a risk of contamination?
▸
Does the knife operate in a corrosive environment?
▸
What issues are you experiencing with your current knife?

A wide range of Granulator Blades in stock

Whether you’re processing plastics, chemicals or pharmaceuticals, Fernite delivers the high-performance blades you need to keep your machines running at their best. Our expertise ensures your granulator blades last longer, require less maintenance, and deliver precise, consistent cutting, every time.
