Background
Graphene is a sheet-like two-dimensional material in which carbon atoms form a hexagonal honeycomb lattice structure with sp2 hybrid orbitals. The special two-dimensional structure causes the graphene to show various special properties such as high strength, high hardness, high thermal conductivity and electrical conductivity; due to these structural and performance characteristics, graphene is known as the most promising potential material for the fabrication of protective coatings, transparent bendable electronic components, ultra-large capacity capacitors, and the like. It is to be added that, strictly speaking, graphene is a single-layer sheet; however, due to the difficulty of preparing single-layer graphene, the few-layer graphene with similar properties is also generally classified into the category of graphene. At present, the preparation method of graphene mainly comprises the following steps: chemical growth methods and physical lift-off methods. Compared with a chemical growth method which is low in efficiency and not suitable for industrial mass production, the physical stripping method mainly adopts cheap graphite as a raw material, and strips graphite layers by applying mechanical force to a graphite crystal to break van der Waals force between the graphite layers to form single-layer graphene or few-layer graphene. Among them, conventional grinding refers to grinding graphite in a mortar grinder, which has disadvantages: firstly, the shearing force is caused by the friction force caused by the pressure, the motor is difficult to drive the pestle body to rotate due to overlarge pressure, the shearing force is limited, and the pestle body is difficult to shear and peel due to the overlarge pressure; secondly, the shearing efficiency is low, and the increase of the amount of the pressed powder can cause insufficient shearing force of part of the powder; thirdly, the pestle body exerts pressure inequality to graphite, produces easily and grinds, and the pestle body exerts pressure to graphite and can make graphite alkene produce structural defect, can make even peel off back graphite alkene and smash for the product edge that makes has more the burr, and the crystal size is little.

The graphene grinding and stripping device can realize large-size stripping of graphene, but the graphene prepared by the technical scheme has impurities with overlarge particles, and the technical scheme cannot grind the graphene at the edge of the annular storage tank, so that the phenomenon of insufficient grinding of the graphene is caused, and the invention is limited.
