洗选厂的浓缩机主要用于洗煤过程中精矿和尾矿的脱水处理,在工艺环节中具有极其重要的作用。通过在浓缩机煤泥水内添加一定量的絮凝剂,使煤泥迅速形成絮团,和煤泥中的粗颗粒一起沉降到浓缩机底部,转动的耙架将沉淀物收集到中心孔,再通过底流渣浆泵将高浓度煤泥水打到压滤机回收。1存在问题重庆松藻煤电公司金鸡岩洗选厂于1986年投产至今,一直使用NG-24型周边辊轮传动耙式浓缩
The concentrator of the washing plant is mainly used for the dehydration of concentrate and tailings in the coal washing process and plays an extremely important role in the process. By adding a certain amount of flocculant in the thickener slime water, the slime rapidly forms flocs and settles with the coarse particles in the slime to the bottom of the thickener. The rotating rake collects the sediment into the central hole and passes through Underflow slurry pump will hit the high concentration of slime water filter press recovery. 1 problems Chongqing Songzao Coal Power Company Jinji Yan washing plant put into operation in 1986 so far, has been using the NG-24 peripheral roller drive Rake concentration
