Title:
粒状凝固スラグの製造方法およびその製造設備列
Document Type and Number:
Japanese Patent JP7448033
Kind Code:
B2
Abstract:
Provided are a method for producing granular solidified slag, whereby slag processing such as heat recovery processing, steam aging processing, and carbonization processing of solidified slag can be efficiently performed, and a production facility line for granular solidified slag. The present invention is characterized by including a mixed solidified material manufacturing step for feeding molten slag S2 and solids S1, M into a mold 1 and causing solidification of the molten slag S2 to progress in a state in which gaps between the solids S1, M are filled by the molten slag S2 in the mold 1 to manufacture a solid/liquid mixed solidified material S, a slag crushing step for crushing the mixed solidified material S into granules to manufacture a mixed crushed material Sg, and a separation step for separating the mixed crushed material Sg in accordance with grain size or material properties into a plurality of mixed crushed material groups to obtain granular solidified slag.
