The present invention relates to an apparatus for recycling aggregates using waste concrete, comprising: a housing including a first outlet on the lower part; a cylinder body slantly arranged inside the housing, comprising multiple discharge holes connecting the inside and the outside, a guiding protrusion protruding in a spiral shape from the inner surface, and multiple crushing protrusions protruding from the inner surface; a hopper installed on the cylinder body to supply waste concrete; and a brush comprising a rotator inserted into the cylinder body, a power source rotating the rotator, and rotating bristles formed on the rotator to separate impurities attached on aggregates with the crushing protrusions by stirring and rubbing the waste concrete in the cylinder body. The waste concrete is divided into the aggregates and impurities by the rotating bristles and crushing protrusions; the aggregates are discharged through a second outlet and a first outlet; some of the impurities are discharged through the discharge hole and the second outlet; and the remaining is filtered by the guiding protrusion to be discharged through a discharge slot and the second outlet. |
