This research seeks to propose a maintenance management model for the Traylor rotary crusher of the primary crushing unit of a company in the mining sector in Arequipa, analyzing the causes and effects of the shutdowns of this machine for maintenance.Since the mining company does not have a specific maintenance plan for this machine, despite this being the main machine of the primary crushing unit, a maintenance plan is proposed to improve its availability. In the years 2014 -2017, the crusher has had less than 96% availability, of the 19.2 hours per day that it can work, despite the fact that greater availability was expected than the machine actually had.To make a maintenance plan for this machine, its activity is analyzed through an analysis of failure modes, effects and criticality (FMECA) and a Pareto analysis of the failures, resulting in main shaft wear, blanket wear and wear. or concave cracks as the most critical faults, among others mentioned in the analysis. The result is a maintenance plan, with activities to be carried out weekly, monthly and quarterly according to the frequency of the failures. With this plan it is calculated that the availability for the year in which it is implemented rises to 97.69%, which is 1.82% more than the availability of the year that showed the highest availability of the years of study.
