▎ 摘　　要

NOVELTY - The device has a first tank body (1) whose lower surface is opened. The lower surface of the first tank body is fixedly connected with a second tank body (2). A lower surface of the second tank body is fixedly installed with a supporting leg (3). An inner part of the first tank body is provided with a grinding mechanism (4) for grinding graphene. The grinding mechanism is provided with two grinding disks and a hydraulic rod. The first tank body is fixedly connected with the first grinding disk. A lower surface of the hydraulic rod is fixedly connected with a connecting column. USE - Graphene powder production device for use in various fields e.g. biomedicine field. Uses include but are not limited to material science, micro-nano processing, energy, and drug delivery fields. ADVANTAGE - The device can close a graphene feeding and grinding space by arranging connecting pipes, vertical cylinders, and a baffle plate to prevent graphene powder from flying up during grinding process, thus reducing waste of graphene powder and improving graphene production efficiency. DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view of a graphene powder production device. First tank body (1) Second tank body (2) Supporting leg (3) Grinding mechanism (4)
