摘要： PROBLEM TO BE SOLVED: To provide a method for pretreating a raw material for sintering, by which an iron ore raw material containing fine powders in an amount larger than before can be dealt with, pellets having pelletization characteristics and strength more improved than before can be prepared and a sintered ore having excellent quality can be manufactured.
SOLUTION: The method for pretreating a raw material for sintering comprises: a first pelletizer 12 where two or more kinds of iron ores each containing coarse grains and fine powders are used as a raw material and the fine powders are allowed to adhere to the coarse grains to be core grains to prepare pellets S; and a second pelletizer 18 where pelletization is carried out using fine powders alone or using mainly fine powders to prepare pellets S. These pellets S and pellets P are used in the pretreatment method. The pellets S are manufactured by regulating the blending amount of the fine powders for the first pelletizer 12, and the remaining fine powders which are not supplied to the first pelletizer 12 are used as a raw material for the second pelletizer 18 by regulating the blending amount of the fine powders for the first pelletizer 12.
