The invention relates to the technical field of grinding wheels and particularly discloses a steel ball grinding wheel formula. The steel ball grinding wheel formula comprises, by weight part, 18-24 parts of a brown fused alumina grinding material, 6-12 parts of a white corundum grinding material, 10-20 parts of a silicon carbide grinding material, 20-30 parts of feldspar, 15-20 parts of clay, 2-5parts of borax glass and 25-40 parts of a binding agent. By means of the steel ball grinding wheel formula, defects of the prior art are overcome; steel ball grinding wheels are made of the brown fused alumina grinding material, the white corundum grinding material, the silicon carbide grinding material, the feldspar, the clay, the borax glass and the binding agent; high durability is achieved, and high grinding efficiency is achieved; and meanwhile, heat resistance is good, and the roasting yield is high.
