2. Describe the principles of jaw crushing and how they impact the performance of a jaw crusher.

Crushing Theory

• In jaw crushing, material is compressed between a fixed jaw and a movable jaw that oscillates.
• The shape and size of the product are determined by the gap between the jaws, known as the “setting”.

Performance Factors

• The optimal setting depends on the material characteristics, such as hardness and size distribution.
• Appropriate jaw plate selection (smooth vs. ribbed) affects the crushing efficiency and product shape.
• Jaw crusher performance is also influenced by factors such as speed, stroke, and feed rate.

3. How do you monitor and control the product size and quality in a crushing plant?

To monitor and control product size and quality, I utilize the following techniques:

• Regular sieve analysis to determine the size distribution of the crushed material.
• Visual inspection of the product to assess its quality and consistency.
• Adjustment of crusher settings, such as jaw gap or impactor speed, based on the desired product specifications.
• Calibration and maintenance of screening and sorting equipment to ensure accurate separation of particles.
• Implementation of quality control procedures, including sampling and testing, to ensure compliance with specifications.

4. Explain the importance of proper lubrication and maintenance for crushing equipment.

• Lubrication reduces friction and wear, prolonging the life of bearings, gears, and other moving parts.
• Regular maintenance prevents breakdowns, minimizes downtime, and maintains optimal crusher performance.
• Scheduled inspections identify potential problems early, enabling proactive repairs and reducing the risk of catastrophic failures.
• Proper maintenance contributes to a safer work environment by preventing accidents related to equipment malfunctions.
• Well-maintained equipment operates more efficiently, consuming less energy and producing a higher quality product.

5. What are the common troubleshooting techniques you employ when a crusher is not performing as expected?

• Visually inspect the equipment for any obvious issues, such as loose bolts or damaged components.
• Check sensors and gauges to ensure they are functioning correctly and providing accurate readings.
• Analyze the product quality and size distribution to identify potential problems with crusher settings or wear.
• Review maintenance records to determine if any overdue repairs or adjustments are needed.
• Consult with the equipment manufacturer or technical experts for guidance and support.

6. Describe the safety protocols and procedures you implement in a crushing plant.

• Conduct regular safety briefings and training sessions for all employees.
