The Jiarui linear vibrating screen is a key piece of screening equipment widely used in industries such as mining, metallurgy, chemicals, food processing, and construction materials. It provides efficient and accurate particle separation, helping improve production quality and operational efficiency.
To ensure stable performance and long service life, proper operation and regular maintenance are essential.
1. Installation and Operational Requirements
Electrical Protection System
The linear vibrating screen should be equipped with a reliable electrical protection device to prevent damage caused by voltage fluctuations or electrical faults.
Anchor Bolt Inspection
During initial operation, anchor bolts should be checked daily to ensure they remain tight and stable. Loose bolts may affect vibration stability and screening accuracy.
Motor Rotation Direction
Before operation, confirm that the motor rotation direction matches the required working direction. If incorrect, adjust the power phase sequence immediately.
Motor Lubrication
Bearings in the motor should be lubricated regularly using lithium-based grease (ZL-3). Lubrication is recommended every two weeks. Sealed bearings do not require additional oiling.
Bearing Inspection
After approximately 1500 hours of operation, bearings should be inspected. If wear or damage is detected, replacement is necessary to avoid equipment failure.
Insulation Resistance Check
If the machine has been idle for a long period, insulation resistance should be tested before restarting. It should be higher than 0.5 megohms using a 500V megohmmeter.
2. Daily Maintenance of Jiarui Linear Vibrating Screen
Before Starting Operation
- Check whether the screen mesh is damaged or worn
- Ensure all locking rings and fasteners are securely fixed
- Confirm the screen deck is properly installed
During Operation
- Monitor for abnormal noise or vibration
- Ensure stable current and smooth operation
- Observe material flow consistency across the screen surface
After Operation
- Clean the screen surface thoroughly
- Remove material residue to prevent blockage and corrosion
- Inspect key components for wear or looseness
3. Regular Maintenance Guidelines
To maintain long-term stability and efficiency, the following inspections should be carried out periodically:
- Check screen mesh for wear, fatigue, or tearing
- Inspect vibration springs for deformation or damage
- Examine machine body for structural fatigue caused by long-term vibration
- Ensure all lubrication points are properly maintained
- Tighten all fastening components regularly
4. Key Maintenance Benefits
