Concentrated quick -witted underflow coarse coal mud recovery system

The utility model discloses a concentrated quick -witted underflow coarse coal mud recovery system, its characterized in that, including coarse coal mud, multiunit swirler, centrifuge, sieve bend, high frequency sieve, one section concentrated machine, the concentrated machine of two -stage process, multiunit swirler is arranged in to coarse coal mud, and coarse coal mud be high concentration underflow and low concentration overflow in grades in the multiunit swirler, and the high concentration underflow is sent into in the high frequency sieve in grades for washing the mixed coal, and duringone section concentrated machine was sent into in the low concentration overflow, it is concentrated quick -witted that the two -stage process is sent into in the overflow of one section concentratedmachine, and the sieve bend is sent into to the high concentration underflow, sieve bend minus sieve coal slime water directly gets into the centrifuge dehydration, and the centrifuge centrifugation is for washing mixed coal a
