Reasons for the rupture of the cone liner of the cone crusher

The rupture of the cone liner in a cone crusher can occur due to various reasons, and it is essential to understand these causes to prevent such failures. Here are some common reasons for the rupture of cone liners:

1. **Overloading:**

- When the crusher is fed with materials that are too large or too hard for the crusher to handle, it can cause excessive forces on the cone liner, leading to cracks or ruptures.

2. **Improper Settings:**

- If the crusher's settings are not adjusted correctly, such as the closed side setting being too small, it can result in the liner being subjected to excessive wear and potential rupture.

3. **Lack of Lubrication:**

- Proper lubrication is crucial for reducing friction between the liner and the bowl, which helps dissipate heat and prevents excessive wear. A lack of lubrication can lead to accelerated wear and ruptures.

4. **Wear and Tear:**

- Over time, the cone liner will naturally wear out due to the abrasive nature of the material being crushed. Continuous operation without replacement can lead to the liner becoming thin and eventually rupturing.

5. **Material Compatibility:**

- The material of the cone liner must be compatible with the material being crushed. Some materials, such as certain abrasive or corrosive substances, can accelerate wear on the liner.

6. **Blocking or Obstructions:**

- If the crushing chamber becomes blocked, the cone liner can be subjected to unexpected forces as the crusher tries to clear the obstruction, potentially leading to ruptures.

7. **Vibration and Misalignment:**

- Excessive vibration or misalignment in the crusher can cause additional stress on the cone liner, which can lead to cracks and ruptures.

8. **Inadequate Replacement Timing:**

- failure to replace the liner at the appropriate time, based on wear indicators or manufacturer's recommendations, can lead to ruptures due to excessive wear.

9. **Quality of Liners:**

- Low-quality or defective cone liners may not withstand the forces applied in the crusher and can therefore be more prone to rupture.

10. **Operational Errors:**

- Operational errors, such as incorrect feed size or incorrect operation of the crusher, can contribute to the rupture of cone liners.

To prevent cone liner ruptures, it is essential to follow proper operational procedures, including regular maintenance, monitoring of the crusher's performance, and replacing liners when they show signs of wear. Additionally, using liners that are suitable for the specific application and materials being processed can greatly reduce the risk of ruptures.
