| Abstract: | Take the partial circulation of centrifuge de-watering and hyperbaric filtration of flotation concentrate as an example,an equation derived for calculation of coefficient of circulation,relation between the solid content in centrifugal liquid and filtrate vs circulating load quantitatively defined,and influence of partial circulation on coal cleaning pointed out;introduced is the special feature of the mould of "2+2" for slime-water treatment,by application of which this partial circulation in coal cleaning production thoroughly eliminated. |

| Keywords: | coal preparation plant slime-water flowsheet partial circulation coefficient of circulation mould of "2+2" |
