Three Key Maintenance Points to Enhance the Lifespan of Impact Crushers

In the context where the recycling of construction waste is becoming increasingly important, the PF - 1315 impact crusher, manufactured by Zhengzhou Kuanglian with thirty years of craftsmanship, has emerged as a core device for efficiently processing concrete, bricks, and steel scrap. It utilizes high - wear - resistant materials and digital precision machining technology. This article will guide you through the practical application of impact crushers in construction waste treatment, emphasizing the combination of technical principles and daily maintenance.

1. Rotor Status Monitoring

The rotor is the heart of the impact crusher. Regular monitoring can significantly extend its lifespan and improve the efficiency of the entire machine. According to industry research, when the imbalance of the rotor exceeds 5%, the vibration of the crusher increases by 25%, and the wear of components accelerates by 30%.

**Practical Tip**: Check the rotor balance every 200 operating hours. You can use a professional dynamic balancing instrument to detect and adjust the balance. If the rotor blade wear exceeds 20%, it should be replaced in time to ensure stable operation. Refer to the standard GB/T 25033 - 2021 for specific maintenance requirements.

2. Feed Composition Adaptation and Adjustment

The feed composition has a direct impact on the performance of the impact crusher. For example, in urban demolition projects, when the steel content in the material exceeds 15%, the processing efficiency of the crusher drops by 30%. Therefore, it is necessary to adjust the feed according to the actual composition of the material.

**Practical Tip**: Before feeding, use magnetic separators to remove most of the steel in the material. Adjust the feed speed according to the hardness and particle size of the material. When dealing with hard materials, reduce the feed speed appropriately to ensure full crushing.

3. Screening System Optimization

An efficient screening system can ensure that the crushed materials meet the required specifications and reduce the wear of the crusher caused by repeated crushing. A well - optimized screening system can increase the throughput of the crusher by 20%.

**Practical Tip**: Regularly check the screening mesh for blockages and wear. Replace the mesh with a suitable aperture according to the required particle size of the final product. Clean the screening system every 100 operating hours to ensure smooth material flow.

Typical Working Condition Simulation

Let's take a city demolition project as an example. The construction waste contains a large amount of steel bars and concrete. By using the above three maintenance methods, we first monitor the rotor to ensure its balance. Then, we use a magnetic separator to remove steel bars from the feed and adjust the feed speed. Finally, we optimize the screening system to ensure that the crushed materials meet the requirements for recycled aggregates.

By following these maintenance methods, you can significantly reduce the failure rate of the PF - 1315 impact crusher, improve the output efficiency of recycled aggregates, and maximize the return on investment of each device. Zhengzhou Kuanglian's thirty - year - long craftsmanship ensures the stable operation of every PF - 1315 crusher.
