The invention relates to a vane type rotor set structure of a crusher, belonging to the technical field of crushers. The vane type rotor set structure comprises a main shaft, hammer connecting plates, wind deflectors and vanes, wherein the hammer connecting plates are installed at one end of the main shaft in an intersected manner, the vanes are installed at the other end of the main shaft, the rotation directions of the vanes are consistent with the working rotation direction of the main shaft, the wind deflectors are arranged between the hammer connecting plates, the wind deflectors are U-shaped plates, and the opening directions of the U-shaped wind deflectors are consistent with the working rotation direction of the main shaft. According to the vane type rotor set structure, by additionally arranging the centrifugal vanes and the U-shaped wind deflectors in a rotor set, crushed materials in a crushing chamber are conveyed into a separation device at an accelerated speed under the multiple actions of hammer set casting and airflow driving, such as centrifugal vane cyclone and wind deflector cyclone, and by improving the flow velocity of the materials, the crushing efficiency and the separation efficiency are improved, a circumfluence layer in the crushing chamber is destroyed, and the energy consumption is reduced.
