About 70% of the world's iron production is carried out through sinter plant-blast furnace route. In general, the sinter proportion in the blast furnace feed is up to 70% and the balance constitutes lump iron ore and pellets. Thus, sinter quality and the productivity are always a challenge for the sinter makers.
