Method for producing general cement clinker by partially replacing iron correction raw material with iron oxide slag
The invention discloses a method for producing general cement clinker by partially replacing an iron correction raw material with iron oxide slag. The method comprises the following steps: blending following raw materials in percentage by mass: 83-92% of limestone, 2.2-2.8% of a mixture of iron oxide slag and ash residues, 5.6-9.3% of sandstone, and 0-9% of shale; mixing, putting the mixture intoa raw material vertical mill for milling; wherein in the mixture of iron oxide slag and ash residues, the weight ratio of iron oxide slag to ash residues is 1:1-6; drying and pre-decomposing the ground raw material, carrying out high-temperature calcination after the decomposition rate reaches 95% or above, and cooling to obtain the general Portland cement clinker. The method can increase the usage amount of iron oxide slag, comprehensively utilizes iron oxide slag, is beneficial to environmental protection, and is convenient to operate, simple in preparation process, low in energy consumption, energy-saving and suitable for mass production of general Portland cement clinker.
本发明公开了一种采用氧化铁渣部分替代铁质校正原料生产通用水泥熟料的方法，该方法将原料石灰石、氧化铁渣和灰渣的混合物、砂岩、页岩，以质量百分比分别为83％～92％，2.2％～2.8％、5.6％～9.3％，0～9％进行调配、混合后，入生料立磨粉磨；所述氧化铁渣和灰渣的混合物中，氧化铁渣与灰渣的重量配比为1:1～6；将粉磨后的生料经过烘干、预分解，在分解率达到95％以上后，进行高温煅烧，然后冷却得到通用硅酸盐水泥熟料。本发明能够提高氧化铁渣的使用量，综合利用氧化铁渣，有利于环境的保护，而且该方法操作方便，制备工艺简单，能耗低，节约能源，适于大批量生产通用硅酸盐水泥熟料。
