Improvement in Machine Performance with the Help of Vibration Analysis of Rotating Machine

In industries excessive vibrations in machines often results in reduced output and hence plant effectiveness is also reduced. Sometimes a simple vibration measurement with limited capability can help in reducing the impact of lost production before getting help of an expert. This is explained with the help of a case study in which the measured vibration spectrum was used to detect the unbalancing in rotor due to deposition of scale on the blades of PH fan in a rotary kiln in a cement industry.
