  • Influence of Coating Granulation Process on Iron Ore

    For better blast furnace performance there has always been a need for better quality raw materials like sinter lump ore and pellets. Among these raw materials the usage of sinter in blast furnace is at higher side compared to other iron bearing materials. As the quality of sinter product improves its usage in blast furnaces also increases.
