The utility model discloses a powder material drying device belongs to chemical industry powder technical field to the cubic material of part influences the problem of fluidized phase's formation whensolving dry material. The device includes centrifuge, band conveyer, conveyer pipe and the drying device who connects gradually, and the conveyer pipe sets up perpendicularly, is equipped with at least one on the conveyer pipe and breaks up the device, breaks up the device and includes motor, the reduction gear that connects gradually and break up the axle, breaks up epaxial being equipped with and breaks up the blade, breaks up the axle and sets up the inside at the conveyer pipe. The utility model discloses a slope setting and the multiple setting of breaing up the axle are guaranteed thatthe cubic material of part whereabouts in -process can all touch to break up the blade, drive through breaing up the axle that to break up the blade high -speed rotatory, with the whole graininesss ofbreaing up into of massive material, guarantee to form good fluidized phase when the material gets into drying device, guarantee final products drying effect, make the drying equipment steady operation.
