三产品煤泥分选分级机处理浮选尾煤的试验研究

以曙光选煤厂的浮选尾煤为研究对象,采用自行研制的三产品煤泥分选分级机,在6种不同结构的锥段下进行了煤泥分选试验。试验结果表明:三产品煤泥分选分级机可以回收浮选尾煤中的粗粒低灰精煤,同时还产生一个细粒溢流和高灰底流;在处理该浮选尾煤时,2号锥段优于其他锥段。

Experimental study on separating flotation tailings by three-product separating and classifying cyclone

Taking flotation tailings collected from Shuguang coal preparation plant as the research object,the laboratory experiments for coal slime separation were conducted employing the three-product separating and classifying cyclone of six different cone section structures.The results showed that: the coarse particles lost into the flotation tailings can be recovered employing the three-product separating and classifying cyclone for coal slime,and at the same time a fine-grained overflow and a high ash underflow are produced.Cone 2# showed better separation results than other cone structure for treating flotation tailings.
