[0002] Graphene is a sp 2 The new material, in which hybrid-connected carbon atoms are tightly stacked into a single-layer two-dimensional honeycomb lattice structure, has excellent optical, electrical, and mechanical properties, and has important application prospects in materials science, micro-nano processing, energy, biomedicine, and drug delivery.

[0003] In the process of graphene production, larger pieces will be crushed and relatively smaller particles will be ground to obtain powdered or small particles of graphene for the next process or use. Graphene is usually ground using a grinding roller to grind the graphene as a whole. However, during the rotating grinding process, the grinding roller may not grind finely enough to meet the use size due to the high hardness of the graphene or excessive accumulation. Some particles may be difficult to grind or difficult to grind and need secondary grinding. Therefore, we designed a graphene raw material grinding device. Utility Model Content
