Wear Mechanisms and Performance of PET Shredder Blade with Various Geometries and Orientations

Shredder blade is the main component of a shredder machine used in plastic recycling. A comparative performance study was conducted on with different geometries and orientations to understand its wear shredding mechanism. Identification loading distribution along blades observed orientations. The microstructure hardness worn cutting edge as-received were characterised by optical microscopy, scanning electron microscopy energy dispersive X-ray, X-ray diffraction analysis testing. mechanism categorised as progressive wear. due abrasive, adhesive, oxidation Recycling efficiency, percentage retention are parameters evaluate various best combination geometry orientation double-edge spiral orientation, which exhibited recycling efficiency at 97.39 ± 0.04%, 69.53 1.32%, 2.61 smaller number recorded severe
