    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 mum, thereby producing S-type granules, and the remaining fines not fed into the first granulator are fed into the second granulator.
