NOVELTY - Method for preparing graphene by stripping high-efficiency grinding body, involves (a) placing the high-efficient grinding body and water and graphite into a ball mill to mix, (b) connecting the high efficiency grinding body with a quadrangular platform, where each plane is connected by an arc transition, where the included angle of two ends in the length direction is 55 degrees, and the included angles of the two ends is 65 degrees, (c) starting the ball mill, setting the rotating speed not higher than 35 revolutions/minute, and grinding and stripping fully to obtain graphene powder, and (d) adding the water-water-graphite mixture into the ball machine to mix. The high-efficiency grinding body is made of steel high aluminum or zirconium oxide. USE - Method for preparing graphene by stripping a high-efficiency grinding body, where the graphene is useful in electrical, thermal and mechanical properties. ADVANTAGE - By using the high-efficiency grinding body to grind at a frequency of a specific range, can effectively peeling the graphite into graphene. By controlling the grinding time, graphene material with different layers can be obtained by adjusting the grinding frequency.
