无传动、免维护深锥高效沉降槽处理选矿拜耳法分离赤泥的试验研究

无传动、免维护深锥高效沉降槽是一种新型深锥沉降槽，其处理选矿拜耳法稀释后赤泥浆液的试验研究表明．无传动、免维护深锥高效沉降槽能够满足选矿拜耳法生产处理稀释后赤泥浆液的需要，具有投资建设费用和运行维护成本低，操作控制简单，劳动强度低，占地面积小的优点，对于选矿拜耳法及拜耳法生产具有广阔的应用前景。尤其对生产场地紧张的老厂技改扩建具有重要意义。

Study of separation of red mud from dressing Bayer process with no driving and maintenance-free high efficient deep cone settler

No driving and maintenance deep cone high efficient settler is a new kind of settler, which can meet the requirements to handle the diluted red mud slurry, It shows the advantages of lower capital investment and operation cost, easy operation and control, lower labor intensity and smaller areas. It will find more applications in dressing Bayer process and Bayer process, in particular, in brown projects.
