Case Study: Granulator Rotor Knife Upgrade for Automotive Plastic Recycling
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.
