Method for making bricks by utilizing waste resources
The invention relates to a method for making bricks by using waste resources, wherein the method comprises the steps: grinding lead-zinc smelting slag into powder by a ball mill until the specific surface area is greater than 100 m<2>/kg, grinding construction waste into powder until the specific surface area is greater than 300 m<2>/kg, mixing with Portland cement, adding a certain amount of water into a stirrer, and mixing, wherein the ratio of lead-zinc smelting slag to construction waste powder to cement to water is 3:2:4:1; and carrying out vibration molding by a brick machine, and carrying out stacking maintenance for 24 hours. The method solves the problem that smelting waste residues and tailings have nowhere to be piled up and pollute the ecological environment, achieves green development and circular economy, saves sand and stone resources, reduces the river channel sand mining scale, and indirectly protects the ecological environment of the Yellow River basin and other riverchannels.
本发明一种利用废弃资源制砖的方法，将铅锌冶炼渣经球磨机磨成粉，达到比表面积大于100m2/kg，将建筑垃圾磨成粉，达到比表面积大于300m2/kg，与硅酸盐水泥混合，在搅拌机中加一定量水混合后，铅锌冶炼渣：建筑垃圾粉末：水泥：水为3:2:4:1，经砖机振动成型，码垛养护24小时即可。本发明解决了冶炼废渣及尾矿无处堆存，污染生态环境的问题，实现了绿色发展，循环经济，节省了砂石料资源，减少河道采砂规模，间接保护黄河流域及其它河道生态环境。
