Treatment system for preparing calcium aluminate from aluminum ash

The utility model discloses a treatment system for preparing calcium aluminate from aluminum ash, which comprises a mixing and batching system, a ball mill, a screening and smelting system, a die and a cooling and screening system, a system discharge port of the mixing and batching system is connected with a feed port of the ball mill, and a discharge port of the ball mill is connected with a system feed port of the screening and smelting system. The aluminum ash recycling system has the advantages that lime and calcium oxide additives are added into the aluminum ash through the mixing and batching system, then the aluminum ash is ground into powder through the ball mill, recyclable aluminum particles are screened through the screening and smelting system, and the aluminum particles are melted and cast in the mold to be recycled; and finally, the calcium aluminate is crushed and sieved into products with required particle sizes through a cooling and sieving system, so that the aluminum ash is effectively and
