NOVELTY - The utility model claims a grinding dispersion machine with high shearing performance for preparing graphene, comprising a bottom plate and a fixing block, the top end of the bottom plate is provided with a first device shell, and the inner part of the first device shell is provided with a first cavity, the inner wall of the first cavity is provided with a first crushing block; and the inner wall of the first crushing block is provided with a first crushing groove; the top end of the first device shell is provided with a feeding shell passing through the first cavity. The graphene preparation is with high shear performance of the grinding dispersion machine; the driving motor drives the first transmission rod to rotate; when the first transmission rod rotates, drives the second crushing block to rotate; at the same time, drives the second transmission rod to rotate through the second crushing block; so that the device can better grind the graphene when using, and then through the second transmission rod to rotate to generate centrifugal force to disperse the graphene, improving the use efficiency of the device.
