Aplicação do planejamento e controle da manutenção em uma fábrica de cimento

Abstract

The business scenario whose competitiveness defines the company's outstanding position, maintenance represents one of the determining factors in the success of results. Maintenance management and its information are essential to strategies, as it is through maintenance that it is possible to anticipate and avoid failures that could cause unforeseen stops. Given this scenario, Maintenance Planning and Control is the sector responsible for managing and controlling all maintenance activities, promoting, ensuring, and guaranteeing increased reliability and availability of the company's assets. The objective of this work is the application of Maintenance Planning and Control in the equipment of a cement factory, in order to define the ideal maintenance techniques in the production system. The research methodology used was a case study, where through interviews with employees and the research of documents registered by managers allowed the collection of information about the processes involved in the production of cement. The delimitation and description of the productive system under study was carried out, to apply the FMEA tool and the Criticality Analysis. From the application of the Analysis of Modes, Effects and Criticality of Failures to the decision that related the criticality of the equipment and the risk of failures for the cement grinding subsystems, it was possible to identify which maintenance techniques should be applied to the operating equipment. The predictive maintenance technique was indicated for 35% of the listed equipment, while the preventive technique presented 41% and the corrective planned 24%. Therefore, based on the percentage of maintenance techniques, the 52-week maintenance map was presented to guide the appropriate periods for performing maintenance.
