How to Identify Whether Bearing Ball Mill is Failure or Not

Time: 2015-02-05

Bearing is a main vulnerable part of ball mill. During the operation of ball mill, the bearing can appear some faults due to stress, assembly or other reasons. In order to reduce the impact on production, we need to judge timely whether the failure occurred ball bearings. This paper introduce some methods to identify whether the ball mill is failing?

This approach requires experienced staff reached to identify the voice of bearing. You can hear clearly the bearing voice by attaching hydrophone or listening rod on the outside of machine. Bearing even a slight peeling and other damage also unusual sounds and irregular sound, with sound measuring device will be able to tell the difference.

Bearing vibration is sensitive to the bearing damage such as Peeling, indentation, rust, crack and wear and tear can respect from bearing vibration measurement. The measured values due to the using condition of bearing and sensor installation location is different, therefore, prior to analysis and comparison the criteria of each machine and get judgment standard.

The above three methods can effectively identify whether the bearing is failure, and thereby preventing in advance and maintenance timely, which can reduce bearing failure rate, and improve the production efficiency of ball mill.
