Method for producing granular solidified slag and production facility line therefor
Provided are a method for producing granular solidified slag and a facility line for producing granular solidified slag, whereby slag treatments such as a heat recovery treatment, a steam aging treatment, and a carbonation treatment can be efficiently performed on solidified slag. The present invention is characterized by comprising: a mixed coagulum production step in which molten slag (S2) and solids (S1, M) are supplied into a mold (1), and the molten slag (S2) is coagulated in a state in which the gap between the solids (S1, M) is filled with the molten slag (S2) in the mold (1), thereby producing a solid-liquid mixed coagulum (S); a slag crushing step in which the mixed coagulum (S) is crushed into granules to produce a mixed crushed product (Sg); and a separation step for obtaining granular solidified slag by separating the crushed mixture Sg into a plurality of crushed mixture groups according to particle size or texture.
本发明提供可以有效地进行对凝固炉渣的热回收处理、蒸汽老化处理、碳酸化处理等炉渣处理的粒状凝固炉渣的制造方法和粒状凝固炉渣的制造设备列。其特征在于，包括：混合凝固物制作工序，向铸模1内供给熔融炉渣S2和固体物S1、M，在铸模1内在固体物S1、M相互间的间隙被熔融炉渣S2填满的状态下进行熔融炉渣S2的凝固而制作固液混合凝固物S；炉渣粉碎工序，将混合凝固物S粉碎成粒状而制作混合粉碎物Sg；以及分离工序，将混合粉碎物Sg根据粒度或材质分离成多个混合粉碎物组而得到粒状凝固炉渣。
