What are some common faults and solutions for vertical shaft impact crushers?

The following are some common faults and solutions for vertical shaft impact crushers:

1. Overheating of bearings

Causes: Poor lubrication, bearing wear, improper installation, overload operation.

Solutions: Check and replenish lubricating oil, replace worn bearings, reinstall bearings correctly, adjust feed rate to avoid overload.

2. Decreased crushing efficiency

Causes: Uneven feeding, impeller wear, excessively low speed.

Solutions: Ensure uniform feeding, replace worn impellers, check motor and transmission system, adjust speed to normal range.

3. Excessive equipment vibration

Causes: Impeller imbalance, loose anchor bolts, material blockage.

Solutions: Balance the impeller, tighten anchor bolts, clear blockage material from the crushing chamber.

4. Product particle size does not meet requirements

Causes: Inappropriate impeller speed, changes in feed particle size, severe wear of wearing parts.

Solutions:

5. Excessive Main Motor Current

Causes: Overfeeding, material blockage in the crushing chamber, transmission component malfunction.

Solutions: Reduce feed rate, clear blockages, inspect and repair transmission components.

6. Lubricating Oil Leakage

Causes: Damaged seals, loose oil pipe connections.

Solutions: Replace seals, tighten oil pipe connections.

7. Abnormal Noise Inside the Machine

Causes: Loose components, foreign objects entering the crushing chamber, damaged bearings.

Solutions: Tighten loose components, remove foreign objects, replace damaged bearings.

8. Drive Belt Slippage

Causes: Insufficient belt tension, excessive load.

Solutions: Adjust belt tension, reduce load.
