【摘要】 鉴于炼焦煤选煤厂的粗精煤泥脱水设备有其特殊的脱泥降灰工艺要求,对适用于粗精煤泥脱水的工艺效果评定指标进行探讨,提出用脱水产物细泥脱除率和粗粒回收率两项指标来取代脱水产物固体产率,并用实例说明其可行性。更多还原

【Abstract】 Because that the dehydration equipment for coarse clean coal slime in coking coal preparation plant had its own special process requirements for desliming and ash reduction,this paper discussed the evaluation index of process effect of dehydration equipment for coarse clean coal slime,it was indicated that we should use the rate of fine slime removal rate of dehydration products and coarse particle recovery rate instead of solid yield of dehydration product,and the feasibility was also demonstrated using practical examples.更多还原
