iron ore sinter crushing strength
Using sinter in place of lump ore and pellets helps to reduce blast furnace fuel rate and CO 2 emissions. Adding fluxed sinter feed to the blast furnace increases softening and melting temperature and improves reduction. Sinter strength plays an important role in deciding PCI rate in the blast furnaces.
