Provided is a method for regenerating recycled aggregate, which mixes zinc or copper slag recycled aggregate with waste concrete recycled aggregate at the same weight ratio and crushing the mixture to reproduce recycled aggregate of high quality. The method for regenerating recycled aggregate comprises: a sorting step(S2) of respectively sorting zinc or copper slag recycled aggregate and waste concrete recycled aggregate to predetermined sizes or less; a mixing step(S3) of mixing the sorted zinc or copper slag recycled aggregate with the sorted waste concrete recycled aggregate; a crushing step(S4) of crushing the mixed recycled aggregates; and a discharge/transfer step(S5) of discharging and transferring crushing completed recycled aggregates. The method further comprises a separation step(S1) of separating various construction and industrial wastes before proceeding the sorting step. The crushing step comprises a first crushing step(S41) of primarily crushing the mixed recycled aggregates and a second crushing step(S42) of crushing again the primarily crushed recycled aggregates to a fine size. |
