Nonmetal grinding medium for cement grinding, and application thereof

摘要: The invention relates to the field of cement grinding, and concretely a nonmetal grinding medium for an application thereof. is prepared from alumina or bauxite as main raw material through burdening, molding calcining; content Al2O3 in 50-98wt%, compressive strength greater than 1000Mpa, Mohs hardness reaches above 7. has following advantages: 1, power consumption machine can be substantially reduced, so energy saving reduction are reached; 2, generation static electricity prevented, electrostatic adsorption efficiency improved; 3, by adopting component, high micro-powder filling effect, quality not influenced even small amount particles shed fall into cement.
