Method for preparing aluminoferrite cement based on red mud and aluminoferrite cement
The invention relates to the technical field of recycling of solid wastes in the aluminum industry, in particular to a method for preparing aluminoferrite cement based on red mud and aluminoferrite cement. The method comprises the following steps: stirring a red mud raw material, and then drying to obtain a dried material with a preset water content; the dried material is ground and then screened, and a mixed material with the preset particle size is obtained; preheating the mixed material, and then cooling to obtain a pretreated mixed material; mixing a fluxing agent with the pretreated mixed material, and then performing extrusion forming to obtain a calcined raw material; calcining the calcining raw material to obtain the aluminoferrite cement; the mass ratio of the fluxing agent to the pretreated mixture is greater than or equal to 0.03; according to the method, the fluxing agent is added into the red mud raw material, so that the adding amount of the red mud raw material can be increased, and the compressive strength of the prepared aluminoferrite cement can be improved.
本申请涉及铝工业固体废弃物的回收利用技术领域，尤其涉及一种基于赤泥制备铁铝酸盐水泥的方法及铁铝酸盐水泥；所述方法包括：对赤泥原料进行搅拌，后进行干燥，以得到具有预设含水率的烘干物料；对烘干物料进行研磨，后进行筛分，以得到具有预设粒径的混合物料；对混合物料进行预热处理，后进行冷却，以得到预处理混合物料；将助熔剂与预处理混合物料进行混合，后进行挤压成型，以得到煅烧原料；对煅烧原料进行煅烧，以得到铁铝酸盐水泥；助熔剂与预处理混合料的质量比≥0.03；该方法在赤泥原料中加入助熔剂，可以提高赤泥原料的加入量，从而可以提高制备出的铁铝酸盐水泥的抗压强度。
