Abstract

This paper describes the new iron ore pelletizing plant of Companhia Vale do Rio Doce, which is currently being erected in São Luís (MA) and is scheduled to start operation in abril de 2002. The plant will have a produção capacity of 6.0 million tons/year of high grade blast furnace and direct reduction pellets. Among the interesting features of the new plant, it must be destacado the largest traveling grate furnace ever built (192 m long and 768 m² of effective grate area) and the use of roller press for ore comminution. The special properties of the Carajás ore enable the plant to have a simplified flow sheet and an optimized compact layout. The São Luís pelletizing plant is one of the important effects implemented by CVRD to strengthen its leading position in the iron ore business worldwide.
