Method for preparing cement clinker from powdery solid waste and steel slag
The invention discloses a method for preparing cement clinker from powdery solid waste and steel slag, and belongs to the technical field of building materials, and the method comprises the following steps: step 1, obtaining raw materials; step 2, mixing the bonding raw material and the powdery solid waste according to a first feeding mode by using mixing equipment; 3, 10-20% of tap water is added into the mixed powder obtained in the step 2, stirring is conducted for a first preset time, then the powder is conveyed into a pelletizer to be pelletized, and a pelletized material meeting a first preset condition is obtained; step 4, placing the granulation material meeting the first preset condition obtained in the step 3 in drying equipment for drying to obtain a dried granulation material; and step 5, continuously feeding the dried granulation material obtained in the step 4 and the steel slag particles into a smoke chamber at the tail part of the rotary kiln according to a first ratio, and feeding into the rotary kiln along with the raw material to complete calcination to obtain the cement clinker, thereby achieving the purpose of eliminating the difficulty in uniformly mixing the powdery solid waste and the fine-particle steel slag with the raw material.
本发明公开了一种利用粉状固废和钢渣制备水泥熟料的方法，属于建筑材料技术领域，包括：步骤1：获得原料；步骤2：利用混料设备，将粘结原料和粉状固废按照第一加料方式进行混合；步骤3：在步骤2获得的混合后的粉料中加入10～20％的自来水，并搅拌第一预设时间之后，将粉料输送至造粒机中进行造粒，获得满足第一预设条件的造粒料；步骤4：将步骤3获得的满足第一预设条件的造粒料放置于干燥设备中进行干燥后，获得烘干后的造粒料；步骤5：将步骤4获得的烘干后的造粒料与钢渣颗粒按照第一配比连续投入回转窑尾部的烟室中，并随生料进入回转窑完成煅烧后，获得水泥熟料，达到了消除粉状固废和细颗粒钢渣与生料难以均匀混合的目的。
