NOVELTY - The mixing device has a rotating shaft, a grinding disc and a grinding ring that are all coaxially arranged with a connecting pipe. An inner diameter of the grinding ring is larger than an inner diameter of rotating shaft. The diameter of the grinding disc is larger than the inner diameter of the grinding ring and smaller than the inner diameter of the connecting pipe. An inner ring of a specific bearing is installed on the rotating shaft. An outer ring of the specific bearing is fixedly connected to an inner wall of the connecting pipe. A blade is installed on one end of the rotating shaft close to a rotating tube (4). The grinding disc is installed on other end of the rotating shaft. The grinding ring is located between the specific bearing and the grinding disc. The grinding ring is sealed and fixedly connected to an inner wall of the connecting pipe. The grinding disc abuts against the grinding ring. USE - Mixing device for graphene production process. ADVANTAGE - The mixing device is provided with excellent stirring effect. The function of removing agglomeration in the raw material through the auxiliary mechanism is realized. The influence of the agglomeration on the mixing of the raw materials is avoided. The function of stirring the raw material through the stirring mechanism is realized. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the mixing device.
