Preparation method of cement clinker by using microwave activated molybdenum tailings
The invention belongs to the technical field of cement, and particularly relates to a preparation method of cement clinker by using microwave activated molybdenum tailings. The method comprises the following specific steps: step 1, adding fluorite powder into the molybdenum tailings, uniformly mixing, and quickly and efficiently activating the molybdenum tailings by microwaves; 2, the molybdenum tailings subjected to microwave activation, limestone, iron powder and coal ash are mixed; 3, fully mixing and grinding the prepared cement raw material to obtain a ground raw material; 4, the ground raw material is subjected to high-temperature calcination and then cooled, and the cement clinker using the microwave activated molybdenum tailings is prepared. According to the method, a small amount of fluorite is added into the molybdenum tailings by applying a microwave field and utilizing existing trace components in raw materials, so that a quartz Si-O structure in the molybdenum tailings is depolymerized and activated, and low-carbon and high-performance preparation of the cement clinker is realized.
本发明属于水泥技术领域，具体涉及一种使用微波活化钼尾矿的水泥熟料的制备方法。该方法具体步骤为：步骤1、将钼尾矿加入萤石粉末，混合均匀后，微波对钼尾矿进行快速高效活化；步骤2、将经过微波活化的钼尾矿和石灰石、铁粉、粉煤灰进行配料；步骤3、将上述制备得水泥生料进行充分混合磨细，得到磨细生料；步骤4、将磨细好的生料经过高温煅烧后冷却，制备得使用微波活化钼尾矿的水泥熟料。该方法通过施加微波场，利用原料中已有微量组分，在钼尾矿中加入少量萤石，使钼尾矿中的石英Si‑O结构解聚活化，实现水泥熟料的低碳高性能制备。
