Reliability Analysis of Conveyor Belt System of Crushing Department

This paper describes reliability analysis of conveyor belt system in Azarabadegan Khoy cement factory. For this purpose, initially the general algorithm presented and then related subsystems and their relationship with each other in terms of various types of networks were evalueted. The required data collected and sorted in chronological order. The results of trend and autocorrelation tests revealed that the assumption of independent and identically distributed is not contradicted for time between failures of CBS1 (CBS: conveyor belt subsystem) and CBS3, but this assumption is valid for CBS2. Thus, classical statistical methods used to analyse the reliability of trend free subsystem and power low process selected for analysing subsystems with trend. Finally, for CBS1 and CBS3 Reliability-based maintenance proposed to achieve the %09 level of operational reliability. In CBS2 evaluation of system condition is carried out by using total time on test plot and corrective maintenance is suggested
