Ceramsite with high-content acid pickling sludge and preparation method of ceramsite
The invention discloses ceramsite with high-content acid pickling sludge and a preparation method of the ceramsite. The ceramsite with the high-content acid pickling sludge comprises 60%-80% of an acid pickling sludge dry basis and 40%-20% of a bentonite dry basis. The acid pickling sludge and bentonite are fully mixed, the mixture is granulated and dried and then enters a sintering kiln, and theceramsite is formed after sintering and cooling. The ceramsite prepared by the method completely conforms to the current specification, and compared with the traditional process, the profit is increased by 3-4 times, the emission is reduced by 3-4 times, and the method has a wide application prospect.
本发明公开了一种具有高含量酸洗污泥的陶粒及其制备方法，所述具有高含量酸洗污泥的陶粒包括60%—80%的酸洗污泥干基，40%—20%的膨润土干基。本发明通过将酸洗污泥与膨润土充分混合，通过混合物料造粒、烘干进入烧结窑，烧结降温后形成陶粒。本发明制备的陶粒完全符合现行规范，并且本发明与传统工艺相比利润提高了3‑4倍，排放降低3‑4倍，具有广阔的应用前景。
