▎ 摘　　要

NOVELTY - The equipment has a jet milling system that is adapted for grinding graphite. A supercritical stripping system is adapted for stripping the ground graphite in a supercritical state to obtain crude graphene. A grading system is adapted for classifying coarse graphene to obtain a thin layer of graphene conforming to the number of layers. A gas compression device (13) is adapted for compressing and conveying the gas in the gas storage device to the airflow grinder. A gas flow control device (14) is adapted for controlling the flow of gas delivered to the airflow mill. USE - Large-scale production device for graphene thin-layer. ADVANTAGE - The thin-layer functionalized graphene can be produced on a large scale, so that the cost of the graphene thin-layer is low, the production efficiency of the graphene thin-layer is high, and the commercial degree of the graphene thin-layer is high. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for large-scale production of graphene thin-layer. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the large-scale production device for graphene thin-layer.
