Preparation method of iron tailing portland cement clinker
The invention relates to the field of building materials, in particular to a preparation method of iron tailing portland cement clinker. The method comprises the following steps: mixing iron tailings, steel slag, lime powder and tin slag, loading the mixture into a grinding machine for grinding, conducting pausing for multiple times in the grinding process, suspending a stirrer at the upper end of the grinding machine, descending the stirrer into the grinding machine for stirring during stirring, then lifting the stirrer, putting the mixture into a drying machine after grinding, conducting drying and dehydrating, taking out the dehydrated material for multiple times in the drying process for flattening, feeding the flattened material into a preheating furnace for preheating and decomposing, then feeding the decomposed material into a high-temperature furnace for calcining, and then quickly conducting cooling to obtain the clinker. According to the method, various impurity tailings are reasonably utilized, the optimal performance use effect is obtained after the optimal proportion is adopted, meanwhile, the method is continuously optimized and adjusted, the performance characteristics of the adopted materials are combined, temperature adjustment is carried out, all stages of grinding, drying and calcining are subjected to careful treatment, raw materials are reasonably utilized, environmental protection is achieved, and also the performance of the product also reaches the optimal state.
本发明涉及建筑材料领域，具体涉及一种铁尾矿硅酸盐水泥熟料的制备方法。将铁尾矿、钢渣、石灰粉、锡渣、混合装入碾磨机进行碾磨，研磨过程中停顿数次进行搅拌，搅拌机悬挂在碾磨机上端，在搅拌时，下降到碾磨机内搅拌后再升起，碾磨后将混合料放入烘干机内，烘干脱水，烘干过程中，多次取出进行压平处理，送入预热炉预热分解，再送入高温炉煅烧，然后再进行速冷，即得熟料。将多种杂质尾料经过合理的利用，采用了最佳的配比后得到最佳的性能使用效果，同时方法也经过不断优化调整，结合采用的材料的性能特点，进行温度调节，碾磨烘干煅烧的各个阶段都经过细致的处理，把原料利用的合理在环保的同时，产品的性能也达到最佳状态。
