Understanding Rapid Granulator Blade Quality

Rapid granulators are renowned for their precision and reliability in plastic recycling and size reduction applications. However, the performance of your Rapid machine depends heavily on blade quality. Inferior replacement blades can lead to inconsistent particle size, increased energy consumption, and frequent downtime.


At Fernite, we’ve been manufacturing granulator blades in Sheffield for over 30 years. Our Rapid replacement blades are reverse-engineered from original equipment specifications, ensuring perfect dimensional accuracy and superior cutting performance. Whether you’re processing PET bottles, HDPE containers, or industrial plastic waste, our blades deliver consistent results.

Frequently Asked Questions from our Customers

How often should I replace my Rapid granulator blades?

Blade life depends on material type, throughput, and contamination levels. Typically, blades should be inspected every 200-400 operating hours and replaced when cutting efficiency decreases or particle size becomes inconsistent.

Can I sharpen Rapid granulator blades instead of replacing them?

Yes! We offer professional granulator knife sharpening service. However, blades can typically only be sharpened 2-3 times before dimensional changes affect performance.

What's the difference between D2 tool steel and carbide tipped blades?

D2 tool steel offers excellent value and performance for most applications. Tipped blades cost more initially but last 3-5 times longer when processing abrasive materials like glass-filled nylon or contaminated recycled plastics.

How do I measure my existing Rapid blades for replacement?

You'll need: overall length, width, thickness, bevel angle, number and position of mounting holes or slots. Take clear photos with a ruler in frame, or send us a sample blade for exact matching.

Are your blades compatible with original Rapid equipment?

Absolutely. Our blades are manufactured to exact OEM specifications and are fully interchangeable with original Rapid blades. Many customers report our blades actually outperform OEM due to superior material quality.

As an expert granulator blade manufacturer, we can develop bespoke products for all applications.
