The invention relates to a grinding material, in particular to a high-strength aluminum grinding ball with glue, which has the raw materials of: 70-80 percent of mature bauxite, 10-15 percent of immature bauxite, 4-7 percent of clay, 2-5 percent of feldspar, 0.5-2 percent of talcum powder, 1-5 percent of calcium carbonate, 0.5-2 percent of barium carbonate, dispersing agent-sodium tripolyphosphate accounting for 3-5 thousandth of the total weight of the raw materials, and adhesive accounting for 3-5 thousandth of the total weight of the raw materials. A preparation method comprises the following steps of grinding, pelleting, molding, burning and the like, wherein the grinding time is 20-30h, slurry is subjected to spray drying granulation through a high tower when in pelleting, the molding pressure is 320 MPa, the burning temperature is 1255 DEG C, heat preservation is carried out for 1h, and the slurry is air cooled to be room temperature and is output from a kiln. The product provided by the invention has high strength, wear resistant, high temperature and pressure resistance, acid and alkali erosion resistance, low water absorption and stable chemical properties. The content of AL2O3 in the product is more than 68 percent, the volume density is 3.0-3.03g / cm<3>, the wear loss is less than or equal to 0.25 thousandth, the compression strength is larger than 1850 MPa, and various performances are superior to those of similar products.
