Summary:To provide a method and an apparatus for manufacturing a sintered ore with high quality of carbonaceous material.SOLUTION: When a sintering raw material obtained by mixing a compression-molded carbonaceous material interior-shaped particles for producing sintered ore containing iron ore powder, a raw material containing CaO and a carbonaceous material with raw material particles for producing sintered ore is charged on a pallet of a sintering machine to form a charging layer, a large amount of the carbonaceous material interior-shaped particles is charged on the lower layer side of the charging layer, and a sintered ore is produced by combustion heat of the carbonaceous material contained in the raw material particles for producing the sintered ore. This is formed into a production equipment of sintered ore formed of a raw material hopper, a compression molding machine for compression-molding carbonaceous material interior-shaped particles, a drum mixer for granulating the usual raw material particles for sintering, and a Dwight Lloyd sintering machine for sintering the mixed sintering raw material.SELECTED DRAWING: Figure 1 【課題】高品質の炭材内装焼結鉱の製造方法および製造設備を提案する。【解決手段】鉄鉱石粉、ＣａＯ含有原料および炭材を含み、圧縮成型された焼結鉱製造用炭材内装成型粒子を、焼結鉱製造用原料粒子に混合してなる焼結原料を、焼結機のパレット上に装入して装入層を形成する際に、前記炭材内装成型粒子を、装入層の下層側に多く装入し、前記焼結鉱製造用原料粒子中に含まれる炭材の燃焼熱で焼結鉱を製造する。原料ホッパと、炭材内装成型粒子を圧縮成型する圧縮成型機と、通常の焼結用原料粒子を造粒するドラムミキサーと、混合された焼結原料を焼結するドワイトロイド式焼結機からなる焼結鉱の製造設備とする。【選択図】図１
