Method for producing cement clinker by employing phosphorus slag
A disclosed method for producing cement clinker by employing phosphorus slag comprises the following steps: (a) crushing rough materials, namely, crushing the rough materials mainly composed of limestone, phosphorus slag, shale, sandstone and iron ore, so as to respectively obtain limestone particle, phosphorus slag particle, shale particle, sandstone particle and iron ore particle; (b) pre-homogenizing the rough materials, namely, performing layered stacking on the various particles obtained in the step (a); (c) preparing raw material; (d) homogenizing the raw material; (e) preheating and decomposing; (f) sintering and obtaining clinker; and (g) grinding the clinker, namely, cooling the sintered clinker, and grinding the clinker to obtain a needed granularity, so as to finish cement production. The method helps to improve the sintering easiness of the raw material, improve the clinker quality, improve the kiln decomposition rate, improve rotary kiln operation ratio, reduce clinker sintering heat consumption and cement comprehensive electricity consumption, increase clinker output, and substantially reduce cement production cost.
