Small hammer crushers are highly efficient crushing equipment used in the mining and building materials industries. Daily maintenance is crucial to ensuring stable operation and extending their service life. Standardized operation and regular maintenance can significantly reduce failure rates and improve production efficiency.
1. Perform a comprehensive inspection daily before startup:
Appearance Inspection: Observe the hammer head and liner for cracks or wear, and the housing for deformation or oil leakage.
Fastener Verification: Use a wrench to tighten the drill rod retaining pin and connecting bolts to prevent loosening that could increase vibration.
Fluid Inspection: Ensure the hydraulic oil level is between the markings and the lubricating oil cup is full. The hydraulic oil should be light amber; if it turns black, replace it immediately.
Functional Test: After startup, perform one or two gentle impact tests to confirm that there are no unusual noises and that the drill rod extends and retracts smoothly.
2. Observe the following key points during operation:
Uniform Feeding: Use a feeding device to ensure stable material flow to prevent skewed or empty strikes that could damage the hammer head.
Control Material Moisture: Moisture levels exceeding 15% can easily clog the screen bars, affecting crushing efficiency. Preventing Metal Foreign Objects: Install an electromagnetic separator to separate metal debris and prevent damage to the liner or rotor.
3. At the end of each day, the following must be performed:
Cavity Cleaning: Remove any blockages in the screen bars and inspect the hammers and liner for wear.
Lubrication and Maintenance: Re-grease the bearings and ensure adequate lubrication at all joints.
Record Inspection: Summarize any abnormalities observed during the day to provide a basis for subsequent maintenance.
The above steps can effectively reduce equipment failures and ensure long-term, efficient operation. Regular maintenance not only reduces repair costs but also improves operational safety.
