Automatización de una planta de trituración de materias primas en una fábrica de cemento

Abstract

Abstract—The majority of industrial processes are being controlled with programmable automatons since more than 20 years. One problem these installations suffer because of the time is the obsolescence of electronic control systems as well as the used software. Thus, when the life expectancy of these devices is over, it is compulsory to change the control system of the plant. The Swiss cement factory of Holcim Gádor in Almería decided to change its control system because of the problems explained before. This work explains how it will be executed the change in this control system in the area of raw material of the plant. Most of the automation work in a running industrial plant must be done before the implementation in site and its start up. It is necessary to define in advance what will be the instrumentation to use, what kind and structure of communication bus will be implemented and what automaton will control the interlocks and starts and stops sequences.
