PROBLEM TO BE SOLVED: To provide a pelletization method of steelmaking slag, by which the steelmaking slag can be pelletized without requiring addition of excess moisture and widening in particle size distribution of pelletized particles can be suppressed.SOLUTION: The pelletization method of steelmaking slag is provided in which moisture is added to steelmaking slag, the steelmaking slag is pelletized and thus raw material for sintering material is obtained. The method comprises mixing and agitating the steelmaking slag and uniformly dispersing the moisture in the steelmaking slag, then further adding moisture to the mixed and agitated steelmaking slag to an adequate moisture content required for pelletization. Preferably, the moisture content in the mixing and agitation of the steelmaking slag after dispersing the moisture uniformly in the slag is made lower than the adequate moisture content. Further preferably moisture of 50-80% of the adequate moisture content required for pelletization is added to the steelmaking slag, the steel making slag is mixed and agitated thereby dispersing the moisture uniformly in the steelmaking slag, then the remaining moisture is added to the steelmaking slag in a pelletization process thereby pelletizing the steelmaking slag. |
