Blade Sharpness Maintenance Guide
Proper care techniques to maintain optimal cutting performance for 4-shaft shredder blades
Material Pre-Treatment
- Remove hard contaminants (metal, stones) before processing
- Control feed quantity for high-hardness materials
- Avoid materials with moisture content >15%
- Pre-screen oversized hard objects
Moisture Limit: Maximum 15% moisture content
Hardness Threshold: Ceramics/thick metals require reduced feed rates
Regular Sharpening
- Soft materials: Sharpen every 200-300 hours
- Medium-hard materials: Sharpen every 100-150 hours
- Use specialized grinding wheels at 30°-45° angle
- Maintain edge thickness ≤0.5mm post-sharpening
Sharpening Warning
Improper grinding angles will cause premature blade wear - always use proper equipment
Edge Angle: 30°-45° cutting angle
Thickness Standard: ≤0.5mm after sharpening
Cleaning & Lubrication
- Daily high-pressure air cleaning of blade gaps
- Weekly application of extreme pressure grease
- Special cleaning agents for sticky materials
- Prevent adhesive buildup on cutting edges
Lubrication: Lithium-based EP grease weekly
Cleaning: Per-shift cleaning for sticky materials
Storage & Spares
- Apply rust inhibitor for long-term storage
- Store in dry, ventilated environment
- Use protective covers for spare blades
- Calibrate 0.1-0.3mm gap during installation
Installation Note
Incorrect blade alignment causes abnormal wear - always verify gap specifications
Storage: Climate-controlled with anti-rust treatment
Installation Gap: 0.1-0.3mm clearance required
Optimal Blade Performance
By following these standardized maintenance procedures, you can ensure maximum blade sharpness, extended service life, and consistent shredding efficiency for your 4-shaft shredder operation.
