摘要： This invention provides a method for pretreatment of raw materials for sintering which comprises providing two or more types of iron ores containing coarse particles and fines as raw materials, adhering the fines to the coarse particles as nucleus particles in a first granulator to produce S-type granules and granulating a material composed of the fines only or a material composed mainly of the fines in a second granulator to produce P-type granules. The amount of the fines to be fed into the first ganulator is regulated so that the average thickness of the fines adhered to the nucleus particles is 50 to 300 µm, thereby producing S-type granules, and the remaining fines not fed into the first granulator are fed into the second granulator.

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.
