本刊讯近日,河北武安市佳业新型建材公司投资达1500万元的尾矿砂蒸压砖项目建成投产。该项目以当地存放尾矿为主要原料,掺加粉煤灰、石粉等废渣,通过压制成型、高温高压处理工艺生产尾矿蒸压砖,工业废渣添加率达到90%以上。主要产品为KP1多孔砖和标砖,还可生产仿古砖。该项目可年生产蒸压砖5000万块标砖,年利用各类工业废渣11万吨。
Recently, our company invested more than 15 million yuan tailings sand autoclaved brick project in Jiaye New Building Materials Co., Ltd of Wuxing, Hebei Province to put into operation. The project uses tailings as the main raw material for local storage and mixes fly ash, stone powder and other waste residues to produce tailings autoclaved brick through press-forming and high-temperature high-pressure treatment. The added rate of industrial waste reaches more than 90%. The main products for the KP1 porous brick and standard brick, antique tiles can also be produced. The project can produce 50 million pieces of autoclaved bricks annually, and annually use 110,000 tons of various types of industrial wastes.
