Sinter Quality and Process of Sintering Iron Ores – IspatGuru

Nov 21, 2014· Nov 21, 2014· The size of iron ore affects the sintering properties. An increase in the size of iron ore promotes the productivity of sinter, but can reduce the tumbler strength slightly and save a little coke. The mineralogy of sinter can more easily be predicted from its chemical composition than its physical and chemical properties.
