Zusammenfassung:	To provide a manufacturing system of a cement composition capable of manufacturing easily a cement composition effective for elution reduction of hexavalent chromium.SOLUTION: A manufacturing system 100 of a cement composition includes a cement clinker firing part 70 for obtaining cement clinker by firing a raw material, a desulfurization part 60 for obtaining slurry containing a sulfite compound by allowing raw material slurry to absorb sulfurous acid gas contained in exhaust gas from the cement clinker firing part 70, and a pulverization part 50 for obtaining the cement composition by pulverizing a compound containing cement clinker and slurry.SELECTED DRAWING: Figure 1 【課題】六価クロムの溶出低減に有効なセメント組成物を簡便に製造することが可能なセメント組成物の製造システムを提供すること。【解決手段】原料を焼成してセメントクリンカーを得るセメントクリンカー焼成部７０と、セメントクリンカー焼成部７０からの排ガスに含まれる亜硫酸ガスを原料スラリーに吸収して、亜硫酸化合物を含むスラリーを得る脱硫部６０と、セメントクリンカーとスラリーとを含む配合物を粉砕してセメント組成物を得る粉砕部５０と、を備える、セメント組成物の製造システム１００を提供する。【選択図】図１
