MANUFACTURING METHOD OF SINTERED ORE

To provide a manufacturing method of a sintered ore capable of achieving further enhancement of productivity by preventing burning unevenness of a sintering raw material with improvement of a method described in patent literature 2.SOLUTION: There is provided a method for granulating a sintering raw material containing fine ore and coagulant with a drum mixer 10, and then injecting the same into a sintering machine 13 by a belt conveyor A11, in which the coagulant is transported together with a low moisture sintering raw material by a belt conveyor B12 and post-added into the drum mixer 10. A post-addition position is in a range of 0.8 L to 0.98 L from an injection port of the drum mixer 10 (full length L), mass of the low moisture sintering raw material is 1 time or more of mass of the post-added coagulant and 24 mass% or less of all sintering raw material injected into the sintering machine 13, the belt conveyor B12 has one or more transition part 12a between the coagulant and the low moisture sintering raw material are merged and post-addition into the drum mixer 10, and the belt conveyor A11 has two or more transition parts 11a and 11b between the drum mixer 10 and the sintering machine 13.SELECTED DRAWING: Figure 1 【課題】特許文献２記載の方法を改善することにより、焼結原料の焼けムラを防止して更なる生産性の向上を実現することが可能な焼結鉱の製造方法を提供する。【解決手段】粉鉱石と凝結材を含む焼結原料をドラムミキサー１０にて造粒処理した後、ベルトコンベアＡ１１にて焼結機１３に装入する方法であって、凝結材を低水分焼結原料と共にベルトコンベアＢ１２で搬送してドラムミキサー１０内に後添加する。後添加位置はドラムミキサー１０（全長Ｌ）の装入口から０．８Ｌ〜０．９８Ｌの範囲、低水分焼結原料の質量は、後添加する凝結材の質量の１倍以上、焼結機１３に装入される全焼結原料の２４質量％以下、ベルトコンベアＢ１２は、凝結材と低水分焼結原料が合流してドラムミキサー１０内に後添加されるまでの間に一カ所以上の乗継部１２ａ、ベルトコンベアＡ１１は、ドラムミキサー１０から焼結機１３までの間に二カ所以上の乗継部１１ａ、１１ｂを有する。【選択図】図１
