The utility model discloses a pulverized coal slime dehydration system, and relates to a coal preparation plant coal slime washing system. The pulverized coal slime dehydration system mainly solves the problems that in an existing pulverized coal slime dehydration system, the number of used equipment is large, the system is difficult to control, product losses are large, and coal quality is low. The pulverized coal slime dehydration system comprises a classifying screen which is respectively connected with a mixing box and a coal slime barrel. The mixing box is sequentially connected with a heavy medium cyclone, a dehydration sculping screen and a horizontal type centrifuge. The coal slime barrel is sequentially connected with a classifying cyclone, a spiral sorting machine, a pulverized clean coal barrel, a cyclone and a vertical type centrifuge. The spiral sorting machine is further connected with a high-frequency screen. The pulverized coal slime dehydration system is simple in structure and convenient to
