Optimización de la productividad del molino vertical LOESCHE utilizando la metodología del mantenimiento productivo total en la Empresa Unión Cementera Nacional – Planta Chimborazo.

Abstract

This research´s main objective was to optimize the productivity of the LOESCHE vertical mill, using the total productive maintenance methodology at the Unión Cementera Nacional Company-Chimborazo Plant. Through a documental review of the records that are part of the maintenance of the Loesche vertical oven, it was determined that the National Cement Union (UCEM) has a quality management system with ISO 9001 certification. However, it is well known the presence of inconveniences within the maintenance process of the aforementioned mill, which is reflected on the indicators obtained in the period between 2020 and 2023. Once Total Productive Maintenance (TPM) is implemented at the start of 2023, it is feasible to indicate that there is an important increase in the use of the mill, which reaches values over 60% and until 2022, it was 60.8%. However, in 2023, there is an increase in the availability of the mill, which exceeds 80% showing a positive effect in the productivity of the establishment. Moreover, is valid to indicate that the optimization of the productivity of the Loesche vertical mill requires verification of the hypothesis through the use of Chi Square, which shows that there are sufficient data to ensure that productivity of the Loesche vertical mill increases with the implementation of the total productive maintenance methodology. As a conclusion, it is stated that the application of TPM within the tasks associated with the maintenance of the Loesche vertical mill positively affects the productivity of the establishment, which is supported by the so-called pillars of this management tool.
