Abstract The present study investigates the reliability and profit analysis of a cement grinding system with failure in the nine important components namely; Belt Conveyor, Bucket Elevator, Separator, Roller Press, Diverting Gate, Process Fan, Cyclone, Ball Mill and Fly Ash System. Only one type of failure has been considered in each of these components except that in the Diverting Gate. In Diverting Gate, two types of failure- minor and major has been taken into consideration. Also in case of Fly Ash System, occurrence of failure does not always results to the failure of the complete system. Data on failure times and cost of repairs have been collected from Shree Cement Ltd., Khushkhera, Rajasthan, India. The system has been analysed by using semi – Markov processes and regenerative point technique. Mean Time to System Failure (MTSF) and various other measures of system effectiveness have been obtained. Profit is also evaluated and graphical study is made to draw various important conclusions. Top Keywords Reliability, Cement Grinding System, Measures of System Effectiveness, Profit Analysis. Top |
