METHOD FOR PRODUCING COAL ASH GRANULE, AND THE COAL ASH GRANULE
PROBLEM TO BE SOLVED: To apply suitable coloring to a coal ash granule.SOLUTION: There is provided a method for producing a coal ash granula comprising: a coal ash mixing step where coal ash and cement are mixed to produce a powdery coal ash mixture; a coloring material mixing step where a coloring material of a color different from that of the coal ash and cement are mixed to produce a powdery coloring material mixture; a primary granulation step where a primary granule as an aggregate of the coal ash mixture is produced; a reaction water addition step where reaction water is added to the surface of the primary granule; a secondary granulation step where the coloring material mixture is adhered to the surface of the primary granule to produce a secondary granule in which the surface of the primary granule is coated with the coloring material mixture; and a reaction step where the cement in the secondary granule and the reaction water are brought into hydration reaction to produce a coal ash granule.SELECTED DRAWING: Figure 4
【課題】石炭灰造粒物に適切な着色を施す。【解決手段】石炭灰造粒物の製造方法は、石炭灰とセメントとを混合して粉体状の石炭灰混合物を生成する石炭灰混合ステップと、石炭灰と異なる色の着色材とセメントとを混合して粉体状の着色材混合物を生成する着色材混合ステップと、石炭灰混合物の集合体である一次造粒物を生成する一次造粒ステップと、一次造粒物の表面に反応水を添加する反応水添加ステップと、一次造粒物の表面に着色材混合物を付着させて、一次造粒物の表面に着色材混合物が被覆された二次造粒物を生成する二次造粒ステップと、二次造粒物中のセメントと反応水とを水和反応させて、石炭灰造粒物を生成する反応ステップと、を有する。【選択図】図４
