NOVELTY - the production device of the utility model relates to graphene processing technology field, and claims a graphene material, comprising a device shell. Production device of the graphene material, the rotating motor is electrified to rotate so that the rotating shaft to rotate, the rotating shaft drives the rotating gear to rotate, the inner cylinder under the common action of the rotating gear, transmission gear and the fixed gear ring to rotate; and the inner cylinder there is rotation speed difference between the rotating shaft, so that the rotating shaft and the inner cylinder to generate relative displacement so as to make the raw material is grinded into powder under the action of the grinding wheel, and through the hollow cavity, a pressure spring, a baffle, a connecting rod and a movable block so that the grinding wheel is always tightly jointed with the inner cylinder; Compared with the traditional grinding device, the device has no gap, so that the raw material is fully grinding in the inner cylinder, and in the process of grinding by pressure spring force so that the grinding is more fully, the device through a series of mechanical structure so that the raw material is fully grinding, the grinding efficiency is high.
