▎ 摘　　要

NOVELTY - Device has procesed mixed slurry comprising graphite (2) and surfactant, received mixed slurry (1) in accommodating groove (10), pressurizing unit (20) is communicating with the accommodating groove, provided pushing force to the accommodating groove to perform a pressurizing stroke on the mixed slurry and connection with the accommodating groove. The nozzle is configured to discharge the mixed slurry from the accommodating groove at a high speed, where pressing force is 500-1000 megaPascal, pressing stroke presses the accommodating groove. The graphite is rubbed with each other to form a portion of the graphite to form a first portion of graphene (4), and another portion of the graphite is separated by a shear force to form a second portion of graphene. USE - Device for producing graphene. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for producing graphene, which involves: (A) mixing graphite and a surfactant to form a mixed slurry, and adding mixed slurry into a containing groove; (B) providing a pushing pressure to the holding groove to the mixed slurry to a pressurizing stroke, and finishing pressurizing stroke of the mixed slurry by a pressurizing unit through a connecting nozzle which is connected with the holding groove and high speed discharge from the containing groove at 500 to 1000 megaPascal; (C) extrusing graphite in the containing groove to make the pressurizing stroke and mutual friction, making the graphite portion forms a first unit of graphene; and (D) separating other unit of graphite by a shearing force through the nozzle to form a second portion of graphene. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a device. Mixed slurry (1) Graphite (2) First portion of graphene (4) Accommodating groove (10) Pressurizing unit (20)
