A concrete recycling system and a method of use thereof is disclosed. The concrete recycling system may recycle aggregates and sand from fluid-concrete based on their grain size. Particularly, the concrete recycling system may have a slurry refiner that allows for the finer aggregates in the fluid-concrete to be recycled. The fluid-concrete may be diluted by water and fed to the slurry refiner via a fluid outlet having a turbulent discharge. The slurry refiner may allow the finer aggregates to settle to the bottom of said device for an auger system to uniformly mix the aggregates and transfer them along the length of the slurry refiner. The uniformly mixed slurry may then be pumped to a hydrocyclone to separate the finer aggregates from the cement and water in the slurry.
