An automotive shredder residue recycler in Germany was getting 3 days from a D2 rotor knife. The fix was a YG15 carbide rotor + YG10X bed, 4-edge reversible geometry, and a torque-wrench discipline. 22 days. The case study walks through the audit, the trial, the result, and the surprising downstream impact on screen wear.

Granulator rotor and bed knives see impact, contamination and abrasive fillers. The right grade, geometry and edge prep separates a 2-week knife from a 6-month one. This guide covers rotor, bed, screen and wear-strip selection for film, rigid, fibre and filled polymer recycling.
