NOVELTY - The utility model claims a grinding device technology field, especially a grinding device for graphene floor coating production, comprising a base, the inner part of the base is provided with a positive motor, the output end of the positive motor is provided with a first fan-shaped gear, the inner part of the base is provided with a reverse motor, the output end of the reverse motor is provided with a second fan-shaped gear, the top part of the base is provided with a grinding chamber. The grinding device for producing graphene floor coating, opening the positive motor and the reverse motor, driving the first fan-shaped gear to rotate in positive direction, and driving the second fan-shaped gear to rotate reversely, so that the inner wall of the grinding chamber and the bottom end of the grinding plate back and forth friction, so as to fully grind the graphene in the grinding chamber, through reciprocating movement of the grinding chamber, the graphene is grinded at the bottom of the grinding plate in the grinding chamber, filtering by the filter plate to make the grinding more uniform, at the same time, increasing the grinding rate.
