Load and No-Load Test Run of Ball Mill - yoyocrusher - 01-12-2018

<p>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 Ultrafine Mill ?</p>

In the no-load test run:<p>1. No-load test run should keep running for 12 to 24 hours. If any problem is found, it should be resolved immediately.</p>
<p>2. After ball mill is conformed qualified, it's time to conduct no-load test run, that is, no balls and no feeding.</p>
<p>3. Inspect the lubrication conditions of all the lubricating parts and make sure there is no oil leakage.</p>
<p>4. The temperature of main bearing should not excess 50 degrees Celsius. If the temperature is too high, cooling measures should be taken.</p>
<p>5. Ensure that there is no significant change in energy consumption and running continuously for more than 8 hours without abnormal accidents.</p>
In the load test run:<p>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.</p>
<p>2. Feed materials according to the discharging condition and avoid unnecessary abrasion and damages to the steel balls and shell liner.</p>
<p>3. Keep ball mill working smoothly, without intensive vibration. If severe shocks occur, check instantly and troubleshoot timely.</p>
<p>4. Inspect each friction part and ensure there is no burning phenomenon.</p>
<p>5. All the seals must be kept in good condition, free from water leakage and oil leakage.</p>
