Maintenance and Care of a Hammer Crusher
1. Daily Inspection
- Bolts & Fasteners: Check and tighten all bolts on the housing, hammers, and rotor before each start.
- Lubrication: Ensure bearings and transmission parts are well-lubricated with clean oil or grease.
- Wear Parts: Inspect hammers, liners, and screens for cracks, deformation, or excessive wear.
2. Regular Maintenance
- Hammer Replacement: Replace or rotate hammers as a set when wear exceeds about 25 % of the original size or when balance is lost.
- Bearings: Clean bearings every two months and refill with fresh grease to prevent overheating or seizure.
- Motor & Belts: Check motor temperature and belt tension regularly; adjust or replace belts if worn.
3. Operating Guidelines
- Feed Control: Keep a steady feed and avoid overloading or letting hard foreign objects enter.
- Start/Stop Sequence: Start the crusher empty, add material only after it runs smoothly; when stopping, cut the feed first, then power down.
- Dust Protection: Keep the work area clean to reduce dust entering bearings or the motor.
4. Seasonal & Long-Term Care
- Cold Weather: Use low-temperature grease and run the machine idle for warm-up.
- Long Downtime: Remove all material, apply anti-rust oil, and cover the machine to keep it dry.
Summary
Regular inspection, proper lubrication, and careful operation are essential to extend the hammer crusher’s lifespan and maintain efficient production.
