<p><P>PROBLEM TO BE SOLVED: To provide a method for manufacturing a sintering raw material used for manufacturing a sintered ore, wherein air permeability of a raw material packed bed is improved when operating a sintering machine, thereby effectively improving productivity of the sintering ore without deteriorating strength and yield thereof. <P>SOLUTION: The method comprises: when granulating a sintering raw material into a granulated sintering raw material in a pseudo-particle form, adding excess moisture to the sintering raw material so as to achieve a moisture value higher than an appropriate moisture value for granulating the sintering raw material, thereby granulating large-diameter pseudo-particles having larger particle size than those formed under the appropriate moisture value; and subsequently subjecting the pseudo-particles to a drying treatment, thereby reducing the moisture value of the large-diameter pseudo-particles after the drying treatment to the appropriate moisture value without increasing the diameter of the particles. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
