How to solve the problem of blockage in the sand making machine?

Blockage in the sand making machine is a common problem that can occur during operation. Here are some methods to solve this issue:

1. **Clean the machine regularly**: Regular cleaning of the sand making machine can help prevent the build-up of materials that can cause blockages. Clean the machine after each use or at regular intervals.

2. **Check the feed size**: Make sure that the size of the material being fed into the machine is within the recommended range. Over-sized material can cause blockages in the machine.

3. **Check the wearing parts**: Wear and tear on the parts of the machine can cause blockages. Regularly inspect the wearing parts such as the impeller, roller, and bearing and replace them when necessary.

4. **Adjust the moisture content**: The moisture content of the material being processed can affect the performance of the sand making machine. If the material is too dry or too wet, it can cause blockages. Adjust the moisture content to the optimal level recommended for the machine.

5. **Avoid overloading**: Do not overfeed the machine as it can cause blockages. Feed the material in a controlled manner to avoid overloading the machine.

6. **Use a vibrating feeder**: A vibrating feeder can help regulate the flow of material into the machine and prevent blockages.

7. **Regular maintenance**: Conduct regular maintenance on the machine to ensure that it is in good working condition. This can help prevent unexpected blockages.

If the blockage problem persists even after implementing these solutions, it is recommended to consult the manufacturer or a professional technician for further analysis and repair.
