Causes and solutions for uneven wear of sand making machine impeller

Sand making machine adopts the dual crushing principle of "stone hitting stone" and "stone hitting iron", which is suitable for processing high-hardness rocks (such as basalt, andesite, etc.). What are the reasons for uneven wear of impeller of sand making machine during operation? How to solve it?
 

Sand making machine

1. Uneven feeding. The material is unevenly distributed when entering the impeller of sand making machine, resulting in heavier wear on one side. To ensure that the material is evenly distributed on the impeller, it can be achieved by improving the design of the feed port or adjusting the feed speed.

2. Different hardness of materials. Materials of different hardness enter the impeller of sand making machine, causing aggravated wear in certain areas. Try to keep the hardness of the material entering the impeller consistent to reduce the additional wear caused by the hardness difference.

3. Unreasonable impeller design. The design problem of the impeller of sand making machine may cause uneven material distribution, resulting in uneven wear. If the uneven wear is caused by the design problem of the impeller of sand making machine, you can consider redesigning the impeller.

4. Damage to the internal parts of the impeller. If the material distribution plate, hammer head and other parts in the impeller are damaged or fall off, the normal distribution of materials will be affected. Check the internal parts of the impeller regularly, and replace them in time if they are damaged or severely worn.

5. Impeller imbalance. Uneven distribution of materials inside the impeller of the sand making machine or damage to internal parts leads to impeller imbalance and aggravated wear. By adjusting the position or weight of the internal parts of the impeller, ensure the overall balance of the impeller of the sand making machine and reduce unnecessary wear.
