The invention provides a ceramic grinding body for gypsum, which is mainly prepared from the following raw material components, Al2O3: 62%~83%, SiO2: 5%~8%, Cr2O3: 0.5%~1.8%, TiO2: 1%~ 1.45%, MnO: 1.51%~1.75%, ZrO2: 1.6%~3.4%, BaO: 1%~3%, Solitaire: 4.6%~7%, ZnO: 2%~2.8%, nano colloidal silicon: 0.5%~1.1%, co-solvent 2%~6%. The ceramic grinding body for gypsum milling of the present invention has light weight and low wear rate, can greatly reduce grinding energy consumption, prolong the service life of the grinding body, and reduce costs; there is no impurity metal iron ion doping in the grinding process, and the quality of building gypsum powder is not affected. Whiteness and strength; ceramic grinding body can also reduce electrostatic adsorption, which is beneficial to improve grinding efficiency.
