Blade Replacement Procedure
Step-by-step guide for safe and effective blade replacement in shredding equipment
Safety Preparation and Equipment Cleaning
- Completely disconnect power supply to equipment before replacement
- Turn off main switch and clearly mark power off area
- Operators must wear protective gloves, goggles, and safety equipment
- Clean residual material and dust from shredding chamber
- Verify blade shaft is completely stationary before proceeding
- Ensure work area is free of obstructions with sufficient space
- Prepare suitable disassembly tools and verify new blade compatibility
Safety First: Always confirm power is disconnected and blade shaft is stationary before beginning any work.
Removal and Inspection of the Old Blade
- Loosen fasteners securing blade using special tool
- Remove old blade step by step in sequence
- Avoid forced prying that could damage blade shaft or mounting surface
- Inspect blade shaft mounting surface and locating pins for wear
- Check for deformation or debris accumulation on mounting surfaces
- Clean surface of oil and debris with appropriate cleaning tools
- Observe wear patterns on old blade to identify potential issues
New Blade Installation and Fixing
- Clean new blades thoroughly before installation
- Ensure cutting edge is free of dents and deformation
- Align blades with cutter shaft according to specified installation direction
- Secure blades sequentially using appropriate fasteners
- Follow principle of even force distribution during tightening
- Gradually tighten each fastener to avoid uneven force
- Adjust blade spacing to ensure proper interlocking gap
Installation Tip: Avoid contact between blade cutting edge and hard objects during installation to prevent damage.
Debugging, Inspection, and Trial Run
- Manually rotate cutter shaft to check for smooth rotation
- Verify no jamming, abnormal noise, or friction
- Confirm all fasteners are secure before power connection
- Connect power supply for no-load trial run
- Observe equipment operating status and blade rotation stability
- Check for wobbling or abnormal vibration during operation
- Add small amount of material for load test after stable no-load run
Final Check: Only resume normal operation after confirming no problems to avoid equipment malfunctions.
