  • Method to lower the formation of clods and the clustering tendency of reducible iron containing agglomerated material, in particular pellets
    Patent number: 6332912
    Abstract: The invention relates to a method for reducing the formation of clods and the clustering tendency of reducible iron-containing agglomerated material, particularly so-called pellets, whereby the reducible iron-containing agglomerated material, following a desulfurization process that takes place after a sintering process during the manufacture of the pellets, is given an outer layer of clustering-reducing material in the form of a liquid suspension of particulate material. According to the invention, a more even distribution of the coating on the surface of the agglomerate is achieved in that the application of the liquid suspension takes place during tumbling in a drum that is designed so that the agglomerate together with the liquid suspension can essentially pass freely through it.
