| Wear Part | Replacement Criteria | Typical Lifespan |
|---|---|---|
| SPC Narrow V-Belts | Cracks > 5 mm, delamination, bubbling, uneven tension (replace all 12 belts together) | 6–12 months |
| Movable / Fixed Blades | Blade wear > 10 mm, chipping; fixed blade grooves affecting output size | 200–500H / 600–1000H |
| Main Bearings | Temperature > 80°C, abnormal noise, radial clearance > 0.5 mm | 12–24 months |
| Screen (5 mm mesh) | Output size > 20 mm, worn/oval holes, structural deformation | 6–12 months |
| A/B Main Blades | Edge wear > 3 mm, reduced capacity, higher energy consumption, larger output size | 1500–2500H |
| Feed Roller Tooth Plates | Worn or broken teeth causing slipping | 1000–2000H |
| Bearing Seals | Grease leakage or dust ingress | 12 months (preventive) |
| Issue | Troubleshooting Steps |
|---|---|
| Motor won’t start | Check power supply, emergency stop reset, thermal relay, wiring connections |
| Sudden shutdown | Check overload protection, material blockage, electrical faults |
| High motor current | Reduce feed rate, inspect blades/bearings, adjust blade clearance |
| Oversized output (>20 mm) | Check screen damage/blockage, inspect blade wear |
| Abnormal noise / overheating | Check bearing lubrication, belt tension, loose components |
