Desarrollo de un plan de mantenimiento en el subproceso de molienda en La Industria Harinera S. A.

Abstract

The purpose of this technical project was to introduce the philosophy of TPM (Total Productive Maintenance) in the company La Industria Harinera SA, for which, 11 of the 12 necessary steps were carried out that are established by the JIMP (Japanese Institute of Plant Maintenance ) in the milling sub-process, which is the most critical of the whole flour-making process. This project established all the necessary parameters for the functional implementation of the philosophy, which are presented in a master plan for the 5 S, autonomous maintenance, planned maintenance, predictive maintenance and quality maintenance. This allowed them to be applied in the other sub-processes that the company owns, in the future if senior management so has it. The activities proposed for the planned maintenance in the B1 grinding bench were proposed based on the calculation of the maintenance indicators MTBF (Mean Time Between Failures) and MTTR (Mean Time To Repairs), these provided important data to perform the OEE calculation. (Global Effectiveness of Equipment) and thus allowed to make maintenance decisions that improve the performance of the equipment and the activities proposed for predictive maintenance, was based on recognizing with the TPM group the best predictive method that fits the parameters of the machine to be carried out maintenance. In each of the planned maintenance processes, standardization and audits were imposed to control and be able to carry out the continuous improvement method in a more efficient way.
