MANUFACTURING METHOD OF CLINKER FINE AGGREGATE, AND MANUFACTURING METHOD OF CEMENT CLINKER
To provide a manufacturing method of clinker fine aggregate that can effectively utilize fine powder generated by particle size adjustment to cement clinker and can minimize an influence of free lime.SOLUTION: A method of manufacturing a clinker fine aggregate of the present invention includes: a step of firing a cement raw material; a step (b) for cooling a cement raw material fired in the step (a); a step (c) of classifying the clinker generated through the step (b) into coarse grains and fine particles based on a classification point within a predetermined range; a step (d) for pulverizing the coarse grains obtained by the step (c) to obtain pulverized fine particles; a step (e) for obtaining cement by mixing the first classified fine particles fine in particle size than fine particles generated at the time of executing the step (c) and a material containing plaster; and a step (f) for obtaining clinker fine aggregate from a mixture obtained by mixing the fine particles obtained in the step (c) and the pulverized fine particles obtained in the step (d).SELECTED DRAWING: Figure 1
【課題】セメントクリンカに対して粒度調整をすることで生じる微粉についても有効に活用でき、なおかつフリーライムの影響を小さくできる、クリンカ細骨材の製造方法を提供する。【解決手段】本発明のクリンカ細骨材の製造方法は、セメント原料を焼成する工程（ａ）と、工程（ａ）で焼成されたセメント原料を冷却する工程（ｂ）と、工程（ｂ）を経て生成されたクリンカを所定範囲内の分級点を基準に粗粒と微粒に分級する工程（ｃ）と、工程（ｃ）で得られた粗粒を粉砕して粉砕微粒を得る工程（ｄ）と、工程（ｃ）の実行時に生成された微粒よりも粒径の細かい第一分級微粉を石膏を含む材料と共に混合してセメントを得る工程（ｅ）と、工程（ｃ）で得られた微粒、及び工程（ｄ）で得られた粉砕微粒を混合した混合物からクリンカ細骨材を得る工程（ｆ）とを有する。【選択図】 図１
