High-Quality Granulator Blades for the Plastic Recycling Industry

Fernite offers 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.

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.

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.
