When a twin-shaft shredder is in operation, the blades are subjected not only to impact and abrasion from the material but also to wear from friction. Therefore, whether it's a single-shaft or multi-shaft shredder, once in use, these two forces acting simultaneously will inevitably cause wear to the blades over time, with the blade's surface and edges gradually becoming rounded.

Therefore, if the forces acting on a twin-shaft shredder shift and the wear pattern changes, it indicates the blades are nearing the end of their service life. If the output material doesn't meet downstream production line requirements, the blades have failed and need to be replaced promptly to ensure normal production.

1. Disassembly and Assembly Precautions

   When disassembling and replacing, be sure to protect the alloy head properly. Damage to the alloy head can cause serious damage and result in unnecessary expenses. During disassembly and assembly, be careful to avoid injuries from sharp edges and ensure safe disassembly and assembly.

2. Inspection is Essential

   The first step in maintaining shredder blades is regular inspection. Regular inspections are primarily designed to check the blade's engagement. If any discrepancies are detected, adjustments must be made to prevent damage. Also, ensure the area around the blade is clean and free of debris before installation.

3. Idle Run is Essential

   When inspecting the blade, it's essential to idle the machine for 30 seconds after installation and inspection. If no abnormalities occur during this period, the machine can be restarted and cutting can resume. However, if any unusual noises are heard during idle run, the machine must be stopped for inspection.
