ore needs to be sintered
During iron ore sintering, a packed bed of uniformly dis-tributed granules—composed of a range of iron ore types, ﬂuxes, fuel, return sinter ﬁnes and plant dusts—is trans-formed into porous sintered particles of irregular shape. The yield of the sinter machine (i.e. the percentage sinterThe sintering process converts fine-sized raw materials, including iron ore, coke breeze, line, mill scale, and flue dust, into an agglomerated product, sinter, of suitable size for charging into the .. The input material is typically 70 percent.
