Hopper extension wings can provide several benefits for a mobile crusher on a mine site, including:

1. Increased hopper capacity: By extending the hopper wings, the crusher can accommodate a larger volume of material, reducing the frequency of trips required to empty the hopper.

2. Improved material flow: The extension wings can help to ensure that material flows smoothly into the crusher, reducing the risk of jams and blockages that can cause downtime and maintenance issues.

3. Reduced spillage: With a larger hopper capacity and improved material flow, the risk of spillage can be reduced, improving safety and reducing the need for cleanup.

4. Increased efficiency: By reducing the frequency of trips required to empty the hopper, the crusher can operate more efficiently, increasing throughput and reducing fuel consumption.

5. Improved versatility: With a larger hopper capacity, the crusher can handle a wider range of materials, increasing its versatility and potentially opening up new opportunities for the mine site.

Overall, hopper extension wings can provide several benefits that can help to improve the performance and efficiency of a mobile crusher on a mine site.
