NOVELTY - The utility model model claims a graphene powder grinding device, comprising a bottom plate, the top of the bottom plate is fixedly connected with a vibration box and a pre-processing box, the top of the vibration box is fixedly connected with a grinding box, the top of the pre-processing box is fixedly connected with a feeding pipe, the inner wall of the pre-processing box is provided with a hydraulic cylinder, the end part of the hydraulic cylinder is fixedly connected with a push plate, the side edge of the push plate is fixedly connected with a crushing head, the top part of the pre-processing box is provided with a material pumping pump, the top and bottom of the material pumping pump respectively fixedly connected with a material guide pipe. The utility model model is composed of a hydraulic cylinder and a push plate, the cooperation of the crushing head and the pre-processing tank, so that before grinding the material, it can effectively crush it, so as to effectively improve the subsequent grinding effect, avoids the material particle is too large to be blocked, so as to occur when grinding, causing the grinding mechanism blocked, influence the grinding effect.
