Method for preparing Portland cement clinker by using multi-source nonferrous metallurgical ash
The invention provides a method for preparing Portland cement clinker by using multi-source nonferrous metallurgical ash. The method comprises the following steps: respectively crushing and grinding limestone, shale, sandstone and multi-source nonferrous metallurgical ash until the screen residue of a 75-micron sieve is less than 10%; taking 80-84 parts by weight of limestone, 6-11 parts by weight of shale, 5-10 parts by weight of sandstone and 2-5 parts by weight of multi-source nonferrous metallurgical ash for mixing and homogenizing after grinding; and putting the homogenized cement raw material in an environment of 1300-1350 DEG C for clinker firing, keeping the temperature for 30 minutes after the target temperature is reached, discharging, and quenching in air to obtain the Portland cement clinker. The characteristics of the multi-source non-ferrous metallurgical ash are utilized, the multi-source non-ferrous metallurgical ash is used as the raw material for producing the Portland cement clinker, the burnability and the calcination temperature of the clinker can be reduced, the production energy consumption can be saved, the performance index of cement prepared from the produced clinker is far superior to the national standard, the multi-source non-ferrous metallurgical ash can be efficiently utilized, and the production cost is reduced. And a large amount of multi-source nonferrous metallurgical ash can be consumed.
本发明提供一种利用多源有色冶金灰渣制备硅酸盐水泥熟料的方法，包括如下步骤：将石灰石、页岩、砂岩和多源有色冶金灰渣分别进行破碎，粉磨至75μm筛筛余小于10%；粉磨后原料按照重量份取石灰石80‑84份、页岩6‑11份、砂岩5‑10份、多源有色冶金灰渣2‑5份进行混合均化；均化好的水泥生料放入1300‑1350℃环境下进行熟料的烧成，到达目标温度后保温30min出炉在空气急冷即制得硅酸盐水泥熟料。本发明利用多源有色冶金灰渣的特性，将其作为生产硅酸盐水泥熟料原料，不仅熟料的易烧性和煅烧温度可下降，可节约了生产能耗，生产熟料制备的水泥性能指标远优于国家标准，而且可以高效利用多源有色冶金灰渣，实现多源有色冶金灰渣的大量消纳。
