Beschreibung
Zusammenfassung:	A cement manufacturing system is provided with: a suspension preheater for preheating a cement raw material; a calcining furnace used for calcining the preheated cement raw materials; and a firing furnace for firing the calcined cement raw material. In the cement manufacturing system, granular materials containing dry sludge are put into a temperature region of 600 DEG C or more and less than 800 DEG C of a suspension preheater, and the dry sludge is used as a cement raw material and fuel. 一种水泥制造系统，其具备：对水泥原料进行预热的悬浮预热器；对预热后的水泥原料进行煅烧的煅烧炉；以及对煅烧后的水泥原料进行烧成的烧成炉。该水泥制造系统中，将包含干燥污泥的粒状物投入悬浮预热器的600℃以上且小于800℃的温度区域，将干燥污泥作为水泥原料和燃料使用。
