Regeneration method of aluminum-silicon waste refractory aggregates

The invention discloses a regeneration method of aluminum-silicon waste refractory aggregates, and belongs to the technical field of solid waste recycling. The method comprises the following steps: 1,crushing the waste refractory aggregates; 2, carrying out secondary grinding and screening on the crushed aggregates to obtain a required particle size; 3, putting the screened aggregates into a silica sol solution, and performing stirring in a vacuum environment; and 4, continuously performing soaking in a vacuum environment, taking out the aggregates after the soaking is finished, and drying the soaked aggregates in the vacuum environment. The true and false aggregates obtained by screening are treated to improve the performances of the recycled aggregates, so the fake aggregates in the waste aggregates are recycled, the overall utilization rate of the waste refractory aggregates is increased, and environmental pollution is reduced; and the method has the advantages of simple process and small investment, and t
