Cone crushers are widely used in medium and fine crushing of high-hardness materials such as granite, basalt and metal ore. During long-term high-load operation, various faults are likely to occur, which affect production efficiency. Mastering common faults and their solutions is crucial for ensuring the stable operation of cone crushers.
### Common Faults & Solutions
1. Low Crushing Efficiency: The main reasons are: the feeding amount is insufficient, the crushing cavity is blocked, the liner is worn, and the discharge port is too large. Solutions: adjust the feeding amount to ensure uniform feeding; stop the machine to clean the blocked crushing cavity; replace the worn liner; adjust the discharge port to the appropriate size according to the finished product requirements.
2. Abnormal Noise During Operation: The main reasons are: uneven feeding, loose parts, insufficient lubricating oil, and damage to the eccentric shaft. Solutions: adjust the feeding to be uniform; check and tighten loose parts; add lubricating oil that meets the requirements; stop the machine to check the eccentric shaft, and replace it if it is damaged.
3. Oil Leakage: The main reasons are: damaged oil seal, loose oil pipe connection, and excessive lubricating oil. Solutions: replace the damaged oil seal; check and tighten the oil pipe connection; drain the excessive lubricating oil to the specified level.
4. Overload Protection Triggered: The main reasons are: excessive feeding, large hard impurities entering the crushing cavity, and blocked discharge port. Solutions: reduce the feeding amount; install a magnetic separator to remove hard impurities; clean the blocked discharge port in time.
### Daily Maintenance Suggestions
To reduce the occurrence of faults, it is necessary to do a good job in daily maintenance: regularly check the wear of liners, eccentric shafts and other wearing parts; add lubricating oil on time and replace the lubricating oil regularly; clean the crushing cavity and equipment surface after shutdown; check the electrical system to ensure safe operation.
