1.1 Pre-Operation Inspection

Before starting the machine, conduct a comprehensive inspection:

• Check that the grinding chamber, classifier, and nozzles are clean and properly installed.

• Ensure that air supply, vacuum system, and electrical connections are intact.

• Inspect bearings, motor, and seals for wear or damage.

1.2 Start-Up Procedure

1. Power on the control panel and activate the air supply.

2. Run the system in idle mode to check airflow, motor function, and safety interlocks.

3. Gradually introduce material into the feed hopper to avoid overloading.

1.3 Grinding Operation

• Adjust the classifier speed according to the desired particle size.

• Monitor air pressure, feed rate, and vacuum collection for consistent performance.

• Maintain a steady material feed to prevent uneven grinding or clogging.

1.4 Shutdown Procedure

1. Stop the material feed and allow the chamber to clear of residual powder.

2. Power off the motor and air supply.

3. Disconnect electrical connections before performing any cleaning or maintenance tasks.

1.5 Operation Tips

• Always wear protective equipment when handling powders.

• Avoid feeding moist or oversized particles.
