The sand making machine is a specialized piece of equipment that requires a well-trained operator. Improper operation can lead to accidents. Below are the guidelines provided by Luoyang Dahua Heavy Industry for the correct operation of the sand making machine.
1. Pre-Start Checks: Before starting the machine, ensure that the vortex chamber inspection door is securely closed.
2. Impeller Direction: Verify the impeller's rotation direction through the feed opening. It should rotate counterclockwise. If it does not, adjust the electrical connections accordingly.
3. Starting Procedure: Always start the sand making machine without a load. Only feed materials once the machine is running smoothly. The correct start-up sequence is:
- Discharging device
- Sand making machine
- Feeding device
The stop sequence should be in the reverse order.
4. Material Size Control: Strictly control the size of the feeding materials. Do not use materials larger than the specified size to prevent blockages in the impeller and central feeding passages, ensuring even material distribution.
5. Feeding Operation: If the discharging device stops, immediately cease material feeding.
6. Monitoring for Issues: If you notice excessive vibration or abnormal noise during operation, stop the machine immediately and conduct a thorough inspection.
7. Lubrication: Apply lubrication grease after each working shift to extend the machine's service life and ensure proper operation.
