Ерөнхий илрэлүүд
Тоног төхөөрөмжийн тэгш бус чичиргээ
Чичиргээ, гэнэт зогсолт эсвэл тасралтгүй чичиргээ
Ерөнхий шалтгаанууд
Вибраторын тэнцвэргүй байдал эсвэл гэмтэл
Төвөөс хазайсан жинүүд зөрүүтэй байна
Суларсан боолтын шураг эсвэл тогтворгүй суурь
Spring fatigue, suspension component deterioration
Шийдлүүд
Check and adjust the consistency of the eccentric block angles on both left and right exciters
Periodically tighten anchor bolts and foundation bases
Replace aged springs, buffers, and vibration-damping devices
Inspect and clean vibration motor bearings and fasteners
Note: Since vibrating screens are “mechanical resonant systems,” unstable vibration often accelerates damage to other components. Therefore, troubleshooting should be conducted promptly.
4. Screen Mesh and Sдэлгэц Box Wear Excessively Fast
Боломжит шалтгаанууд
High hardness and sharp edges of raw materials
Concentrated feed drop points are causing excessive localized impact
Insufficient screen surface support or vibration isolation
Improvement Measures
Use more wear-resistant screen mesh (high-manganese steel/polyurethane/composite materials)
Distribute material evenly to avoid localized impact
Add cushioning liners, wear strips, and reinforced vibration isolation components
5. Throughput Below Design Capacity
Performance
Actual TPH is significantly below the theoretical design
Large fluctuations in production capacity
Ерөнхий шалтгаанууд
Insufficient screen area or improper layer configuration
Uneven feeding or material blockage
Inefficient system process configuration (excessive material recirculation)
Optimization Solutions
Evaluate whether to increase the screen area or adjust the screen layer count
Configure a rational feeding system (vibrating feeder + buffer device)
Redesign the screening process to reduce excessive recirculation
6. High Noise and Unstable Operation of Vibrating Screen
Ерөнхий шинж тэмдгүүд
Operating noise exceeds normal levels
Abnormal resonance occurs in the machine body
Underlying Causes
Сул бэхэлгээ
Insufficient bearing lubrication or wear
Failed spring suspension
Improvement Measures
Regularly inspect the tightness of anchor bolts and connecting components
Periodically replenish bearing grease and replace aged springs
Replace worn bearings and failed suspension springs
Install vibration isolation pads on foundations and supports
7. Excessive Vibration and Wear Issues (Advanced Fault)
This condition commonly occurs under continuous heavy loads where the vibrational energy is mismatched with the screening process.
Ерөнхий илрэлүүд
Cracks in screen frames and welds
Frequent spring breakage
Structural fatigue in the machine body
Resolution Approach
During operational design, ensure:
Matching of excitation parameters (frequency/amplitude) with load conditions
Enhanced structural rigidity and stress distribution design for the screen box
Implementation of fatigue life optimization design
8. Deviant Screening and Unstable Product Gradation
Causes
Improper selection of screen mesh size
Uneven material feeding distribution
Poor interlayer transmission
Шийдлүүд
Re-evaluate the screen mesh size design
Improve distribution uniformity on the screen through multi-point feeding
Adjust interlayer spacing and angle to optimize gradation separation
9. Frequent Shutdown and Maintenance, Affecting Production Continuity
Ерөнхий шалтгаанууд
Timely replacement of wearing parts was not carried out
No preventive maintenance plan
Lack of real-time operation monitoring
Шийдлүүд
Establish regular inspection plans
Implement spare parts inventory management
Adopt an online monitoring system for early warning of vibration, temperature and other indicators
Дүгнэлт
A vibrating screen is one of the core pieces of equipment in the crushing and screening system. Its operating status directly determines screening efficiency, production stability, and operating costs. Most problems are not caused by equipment defects, but by incomplete matching of design, installation, operating parameters, мөн maintenance strategies with actual working conditions.
Combined with engineering practice and systematic optimization strategies, Гүйх provides more stable, efficient, and easy-to-maintain vibrating screens and integrated screening solutions for mining, aggregate, and concrete production lines.
