Estratégias de controle no processamento de minério de ferro

Abstract

The Iron Ore Processing is characterized by a long production cycle in integrated continuous process that goes from the mine to the final distribution. Within this context, and since the process is determining the total recovery of the ore as well as the investment return that can be achieved on a plant, this work presents control strategies in order to automate the production and its optimization directed to a typical benefitprocess. The analyses were performed according to the four levels of the automation pyramid system: optimization systems, supervision systems, control systems and instrumentation systems. In addition, not only was it explained the importance of each of these layers, but also it was considered the relationship between them in the industrial automation,always aiming at the operator safety and the potential environmental impact reduction. It was concluded that a good development of the basic and the detailed automation project to maximize the profit of the enterprise is necessary in order to reduce its cost and to add quality improvements to the product and in the course of operation. The goodwork of the design engineer in the early stages of the project results in the reduction of problems of a plant's deployment and maintenance
