利用纯工业废渣烧结砖的生产工艺与粘土砖生产工艺基本一致,所不同的是粘土不须深加工而块状工业废渣须经粉碎加工,再经过按比例掺配,加水、加汽、二次挤泥处理,改善废渣的物理性状,然后才进入成型工段,制成砖坯。原料的粉碎处理与调配:工业废渣大多是块状料,必须经过粉碎加工,使粉碎料的颗粒大小基本符合下列要求,小于0.002毫米的物料占50％左右,小于0.02毫米的物料占25％左右,通过双轴搅拌机加
The production process of using pure industrial waste slag bricks is basically the same as the production process of clay bricks. The difference is that the clay does not need to be deep-processed and the blocky industrial slag must be crushed and then undergo proportionate blending, adding water, steam addition, and secondary extrusion. The mud treatment improves the physical properties of the waste residue before it enters the forming section and is made into a brick. Raw material smashing and blending: Industrial wastes are mostly massive materials and must be crushed so that the particle size of the comminuted material basically meets the following requirements. Materials less than 0.002 mm account for about 50%, and materials less than 0.02 mm account for about 25%. , added by double shaft mixer
