Causes of Failure of Crawler Mobile Screening Plant

Crawler mobile screening plants are essential in the construction, mining, and recycling industries. They offer unparalleled flexibility, mobility, and efficiency in material processing. However, like any machinery, they are susceptible to failures. Understanding the common causes of failure of crawler mobile screening plants is crucial for improving their longevity and performance. This article delves into the primary reasons behind these failures and offers preventive measures.

1. Mechanical Wear and Tear

Causes:

• Intense Operational Demands: Continuous and heavy use leads to wear and tear of mechanical components.
• Poor Lubrication: Inadequate lubrication increases friction and accelerates the degradation of parts.

Preventive Measures:

• Regular lubrication schedules.
• Periodic mechanical inspections.

2. Hydraulic System Malfunctions

Causes:

• Contamination: Dirt and debris entering the system can cause blockages and impair functionality.
• Overheating: Excessive heat can degrade hydraulic fluid, leading to system inefficiency.

Preventive Measures:

• Use of high-quality hydraulic fluids.
• Installation of proper filtration systems.

3. Electrical Failures

Causes:

• Faulty Wiring: Loose or damaged wires can cause short circuits or intermittent failures.
• Component Degradation: Over time, electrical components can degrade due to exposure to the elements.

Preventive Measures:

• Regular electrical system check-ups.
• Protective housing for electrical components.

4. Poor Maintenance Practises

Causes:

• Neglected Routine Maintenance: Skipping regular check-ups diminishes machine health.
• Unqualified Personnel: Inexperienced operators or maintenance personnel can inadvertently cause damage.

Preventive Measures:

• Strict adherence to a maintenance schedule.
• Ensuring only trained personnel handle the maintenance and operation.

5. Environmental Factors

Causes:

• Extreme Weather Conditions: Excessive heat, cold, or moisture can adversely affect the plant.
• Harsh Operating Conditions: Working in rough terrains can strain the machine’s components.

Preventive Measures:

• Employing protective measures like covers and heating elements during operation.
• Regular assessment and adaptation to environmental conditions.

6. Structural Failures

Causes:

• Fatigue of Materials: Repeated stress can cause metal fatigue and structural issues.
• Improper Use: Overloading the plant can cause irreparable damage to its structure.

Preventive Measures:

• Load regulation according to the manufacturer’s specifications.
• Frequent structural integrity assessments.

7. Vibration and Shock

Causes:

• Operational Vibrations: Constant vibrations during operation can loosen components.
• Sudden Shocks: Impacts from heavy materials can cause misalignment or damage.

Preventive Measures:

• Use of shock absorbers and vibration dampeners.
• Implementing a balanced loading approach.

Conclusion

Understanding the causes of failure in crawler mobile screening plants is vital for optimizing their efficiency and longevity. Regular maintenance, adherence to operational guidelines, and employing preventive measures can significantly reduce the risk of failures. By addressing these common causes, operators can ensure their plants operate smoothly, leading to improved productivity and reduced downtime.

If you are looking to enhance the performance and reliability of your crawler mobile screening plant, it is essential to stay vigilant regarding these potential failure points. Investing in quality components and providing adequate training for personnel are crucial steps towards achieving operational excellence.
