▎ 摘　　要

NOVELTY - The device has a main shaft that runs through the center of a filter plate and is slidably connected with the filter plate. An eccentric roller can roll along the filter plate and is always in contact with the upper surface of the filter plate. The outlet of a crushing cylinder (1) is connected to a fine grinding cylinder (13). The fine grinding cylinder is provided with a fine grinding roller. The fine grinding roller is used for grinding a graphene slurry. The bottom of the fine grinding cylinder is provided with a collecting cylinder (15). The collecting cylinder communicates with the fine grinding cylinder. The bottom of the collecting cylinder is provided with a feeding port (16). USE - Graphene slurry grinding device used in electronics, magnetics, optics and biology. ADVANTAGE - The device prevents the graphene from peeling off repeatedly grinding, and improves the quality of the graphene. The device generates vibration to prevent raw material from blocking, when the eccentric roller impacts the graphite raw material. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a preparation method of graphene slurry by using the graphene slurry grinding device. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the graphene slurry grinding device. Crushing cylinder (1) Fine grinding cylinder (13) Collecting cylinder (15) Feeding port (16)
