After the installation is completed, ball mill needs to have an all-around inspection. After everything is done well, it's time to carry out the test run. Before commissioning, we must have a good preparation and inspection in advance. What problems should we note in the load and no-load test run of ball mill?

In the no-load test run:

1. No-load test run should keep running for 12 to 24 hours. If any problem is found, it should be resolved immediately.

2. After ball mill is conformed qualified, it's time to conduct no-load test run, that is, no balls and no feeding.

3. Inspect the lubrication conditions of all the lubricating parts and make sure there is no oil leakage.

4. The temperature of main bearing should not excess 50 degrees Celsius. If the temperature is too high, cooling measures should be taken.

5. Ensure that there is no significant change in energy consumption and running continuously for more than 8 hours without abnormal accidents.

In the load test run:

1. Feed 20-30% of the specified load of balls and materials into the ball mill and keep it running for 8 to 10 hours. After it runs normally, add a proper amount of steel balls.

2. Feed materials according to the discharging condition and avoid unnecessary abrasion and damages to the steel balls and shell liner.

3. Keep ball mill working smoothly, without intensive vibration. If severe shocks occur, check instantly and troubleshoot timely.

4. Inspect each friction part and ensure there is no burning phenomenon.

5. All the seals must be kept in good condition, free from water leakage and oil leakage.
