Bearing Fault Diagnosis of a Mine Stone Crasher by Vibration Condition Monitoring Technique

To maintain an efficient operating unit and avoid failure of mineral critical equipment, it is necessary to maintain the critical parts of that equipment. Recently, rotary machines with rolling bearings have become highly advanced and the environments in which the machines are being used have diversified. The improvement of the reliability of the rolling bearings for special environments such as corrosive, high temperature, high speed, or high vacuums environments, has become very important. The objective of this research was to investigate the correlation between vibration analysis and fault diagnosis. This was achieved by vibration analysis of two bearings of stone crasher in Pirbakran mineral mine company. The vibration analysis was run under regular interval during stone crasher life. Overall vibration and numerical data produced by vibration analysis were compared with vibration spectra in a standard condition of healthy machine, in order to evaluate the effectiveness of the vibration condition monitoring technique. The results of this paper have given more understanding on the dependent roles of vibration analysis in machine faults predicting and diagnosing.
