APLICAÇÃO DE MÉTODO SIMPLIFICADO DE DETERMINAÇÃO DE WI NA PREVISÃO DE DESEMPENHO DOS MOINHOS DE BOLAS DA USINA DO SOSSEGO.

Over the years Vale S.A. has developed a methodology for scaling industrial comminution circuit that is being constantly improved and implemented in developing new routes and process optimization of circuits in operation. This work will be given a focus on the methodology of simplified balls mill Work Index (WI Anaconda) in performance prediction of Sossego Plant ball mill. The great advantage of this methodology is to reduce the time and weight to determine the energy consumption in ball mills, whose values can be used in studies of variability, geometallurgy and design and control of industrial grinding circuits.
