crusher setter Interview Questions and Answers

1. What is your experience with various types of crushers (jaw, cone, impact, etc.)?

   • Answer: I have extensive experience with jaw, cone, and impact crushers. I'm familiar with their operational principles, maintenance requirements, and common troubleshooting issues. My experience includes [mention specific crusher models and brands, if applicable] and working with different sizes and capacities.

2. Describe your experience setting up and aligning crushers.

   • Answer: I have [number] years of experience setting up and aligning various crusher types. This includes precise adjustments of the crusher components, ensuring proper clearances, and verifying alignment using surveying tools and precision measuring equipment. I am proficient in using shims, wedges, and other alignment tools to achieve optimal performance.

3. How do you ensure the safety of yourself and others while working on crushers?

   • Answer: Safety is my top priority. Before starting any work, I always conduct a thorough risk assessment, ensuring all lockout/tagout procedures are followed. I wear appropriate PPE, including safety glasses, hard hats, gloves, and hearing protection. I'm familiar with emergency procedures and know how to respond to various hazards.

4. Explain the process of changing crusher liners or mantles.

   • Answer: The process involves safely isolating the crusher, removing bolts and securing the old liners/mantles, cleaning the crusher chamber, carefully installing new liners/mantles, ensuring proper alignment and securing them with bolts, and finally inspecting for any damage or misalignment before restarting the crusher.

5. How do you troubleshoot common crusher problems like reduced production or excessive wear?

   • Answer: I systematically troubleshoot issues by checking for things like liner wear, improper alignment, feed rate, material properties, and hydraulic pressure. I use diagnostic tools and my experience to identify the root cause and implement the necessary corrective actions, which may involve adjustments, repairs, or replacement of parts.

6. What are the different types of crusher settings and how do they affect the product size?

   • Answer: Different crushers have different settings, but generally, settings control the gap between crushing surfaces. A smaller gap produces finer product, while a larger gap produces coarser product. Specific settings vary depending on the crusher type (jaw, cone, impact) and manufacturer.

7. How do you maintain crusher lubrication systems?

   • Answer: Regular lubrication is critical. I monitor oil levels, check for leaks, ensure proper oil pressure and temperature, and change oil and filters according to the manufacturer's recommendations. I also inspect components for wear and tear.

8. What are the safety precautions you take when working with hydraulic systems on crushers?

   • Answer: I always ensure the hydraulic system is properly isolated before performing any maintenance or repair. I use appropriate tools and follow safety procedures to prevent high-pressure fluid leaks or accidental activation. I am aware of the risks of hydraulic fluid and take appropriate precautions.

9. How familiar are you with vibration monitoring and its importance in crusher maintenance?

   • Answer: I am familiar with vibration monitoring as a preventative maintenance tool. Excessive vibration can indicate misalignment, bearing failure, or other problems. Regular vibration monitoring allows for early detection of potential issues, preventing costly breakdowns.
