Crusher Hammer Ring Installation and Replacement Tutorial

Preparation

1. Ensure the crusher is completely shut down and the power supply is disconnected for safety reasons.
2. Clean the crusher interior to ensure there are no residual materials to avoid personal injury or damage to the equipment during the replacement process.
3. Prepare a new hammer ring and necessary tools, such as a hammer, wrench, and jack.

Removing the Old Hammer Ring

1. Use a jack or specialized tool to lift the crusher’s rotor and ensure it rotates freely.
2. Depending on the crusher model and design, use an appropriate wrench or tool to remove the bolts or pins securing the old hammer ring.
3. Carefully remove the old hammer ring from the rotor. Be aware that the hammer ring may be sharp due to wear, so wear protective gloves and glasses when handling this procedure.

Installing a New Hammer Ring

1. Check the size and shape of the new hammer ring to ensure it meets the requirements of the crusher.
2. Place the new hammer ring on the corresponding position on the rotor, ensuring proper alignment.
3. Secure the new hammer ring to the rotor with bolts or pins. Ensure the bolts or pins are securely in place, but do not overtighten to avoid damaging the hammer ring or rotor.
4. Check all newly installed hammer rings to ensure they are securely fastened to the rotor.

Restoration and Testing

1. Slowly lower the rotor, ensuring that the new hammer ring does not collide with the crusher housing or other components.
2. Reconnect the crusher to the power supply and perform a no-load test run to observe whether the hammer ring is correctly installed and whether the rotor operates smoothly.
3. After the no-load test run is complete, perform a loaded test run to observe the crushing performance and hammer ring wear.

Notes

1. When replacing hammer rings, follow the equipment manufacturer’s instructions and recommendations.
2. During replacement, regularly inspect and tighten all connections to ensure safe operation of the equipment.
3. Regularly inspect the hammer ring for wear and replace it promptly to prevent further damage to the crusher.
4. During operation, always follow safety procedures and wear appropriate personal protective equipment.
   By following the above steps, you can safely and effectively complete the installation and replacement of your crusher’s hammer ring. Proper maintenance and timely replacement of wearing parts will help improve the efficiency and service life of your crusher.
