NOVELTY - The utility model claims a new graphite in device, especially relates to a kind of one antioxidant expand graphene and preparation system. Including with the cylinder, the mixing cylinder and bottom part along the tangent direction of mixing cylinder has an air inlet, set on cylinder wall of the mixing cylinder set with antioxidants nozzle, the upper end of the mixing cylinder by a discharging pipe connected with the cyclone separator, and the cyclone separator bottom set with holder, upper end is set with outlet. This utility model new advantages relative to existing in the highlight device, make it can expand graphite raw material and antioxidants is mixed more uniformly, antioxidant production efficiency and expand graphite is high, production out of antioxidant expand graphite has more stable and oxidation resistance.
