两级浮选、精煤泥两段脱水工艺在田陈选煤厂的应用实践

Application of two section flotation and two stage dewatering of clean fine coal processes in Tianchen coal preparation plant

详细阐述了田陈煤矿选煤厂两级浮选、精煤泥两段脱水工艺及其工艺特点,并介绍了该工艺的应用效果。生产实践表明,两级浮选、精煤泥两段脱水工艺运行效果良好,两级浮选精煤回收率高,尾煤泥灰分高,从而最大限度地利用了资源,取得了良好的经济效益。

The paper detailed introduced the two section of flotation and two stage dewatering of clean fine coal processes and its features,also described the application effect of the processes.The production result shows that the two section of flotation and two stage dewatering of clean slime processes obtained better operation performance and with the features of high in clean coal recovery rate and low in ash content of tailings,maximally utilized the coal resource and achieved good economic benefit.
