A cylindrical agitator for fine aggregate comprises an external frame, a rotation shaft, a supporting rod, and a rotation blade unit. The external frame is formed with a storage space inside. The rotation shaft is rotated by receiving driving force from the center of the storage space. The supporting rod is extended to the direction of the lower surface of the external frame by fixing the rotation shaft on one side. The rotation blade unit includes a main rotation blade rotated inside the storage space with respect to rotation of the rotation shaft by being fixated on one end of the supporting rod, and formed at a fixed angle with the lower surface of the external frame; and a plurality of auxiliary rotation blades extended in parallel from one end of the main rotation blade. |
