This document presents a proposal for designing an expert system in the Gabriela Mistral Division’s crushing plant belonging to Codelco (Chile) with the objective of maximizing stacked tonnage allowing the improvement of operational variables that directly interact with the crushing process. In addition this study considers the impact that occurs in both the process and operational continuity regarding the standardization of the system. In the first stage a survey and analysis of historic operation data was carried out which allowed the definition of benchmarking indicators. Subsequently both modalities of operation were compared monitoring processed tonnage and detentions related to operational failures. As a result significant differences were observed in the performance of the critical line operating with expert control with a 55% reduction in the detentions referred to operational failures. Added to this is the benefit of low cost and improved quality as the control provides an analysis of the variables in reduced time intervals which is superior to human control. © 2018 by the authors.
