Abstract: CVRD operates a complex of seven iron ore pelletising plants at Vitoria, Espirito Santo, Brazil, all of which have the same flowsheet, together producing 25 million tons of pellets a year. The automation of these plants is described, comprising instrumentation, control and information systems. The advanced control systems using artificial intelligence, including fuzzy logic, expert systems and dynamic physical models. Implementation of the project, lessons learned and improvements in plant performance and energy consumption achieved are described.<br />CVRD operates a complex of seven iron ore pelletising plants at Vitoria, Espirito Santo, Brazil, all of which have the same flowsheet, together producing 25 million tons of pellets a year.
