The invention belongs to the technical field of fluidization, in particular relates to a rotating airflow fluidization device and a flaky material fluidization method and aims at solving the problems that flaky materials can produce electrostatics easily in a fluidization process, adsorption and agglomeration can be caused easily and a fluidization dead zone can be easily formed in the fluidization process. The fluidization device comprises a gas distributor, the gas distributor can enable airflow to rotate and produce rotating airflow, and the flaky materials are driven to rotate by virtue of rotation of the airflow, so that the flaky materials can produce a centrifugal force and are separated from each other, and influence of electrostatic adsorption is eliminated; the rotation of the airflow also can drive the flaky materials in the fluidization dead zone at the bottom of the fluidization bed, so that the fluidization dead zone is eliminated. The rotating airflow fluidization device provided by the invention is simple and scientific in structure, strong in industrial applicability and applicable to popularization and application.
