How to test the ball mill under the no-load test running

After the ball mill is idling for a specified time, you can stop the ball mill, carefully check all working parts, tighten the liner bolts, and eliminate the defects found. After there is no problem with the ball mill idling, the load test can be carried out. Load test run should be gradually added until full load.
