Grading wheel and sand mill with same

The invention discloses a grading wheel and a sand mill with the grading wheel, and relates to the technical field of sand mill accessories, and the grading wheel comprises a supporting assembly, a blade assembly, a driving assembly and a pushing assembly. The invention further discloses a sand mill with the grading wheel. The sand mill comprises a barrel, a top cover and a driving motor. The supporting assembly is arranged in the sand mill, a plurality of blade assemblies are arranged in the supporting assembly, materials ground by the sand mill move into the blade assemblies and are driven by the blade assemblies to rotate, and large and small particles in the materials are classified under the action of centrifugal force; by arranging the adjustable blade assemblies, the gaps between the blade assemblies can be adjusted according to the hardness characteristics of materials, and accurate control over material grading is achieved; and the distance of the backflow materials can be adjusted through the pushin
