▎ 摘　　要

NOVELTY - Device comprises a mounting base (1), a main body mechanism (2), a feeding mechanism (3), a driving mechanism (4), a driven crushing mechanism (5), and a stirring mechanism. The top of the mounting base in the form of a gourd-shaped plate is fixedly mounted with the main body mechanism for arranging other mechanisms. The feeding mechanism for feeding the device is fixedly mounted on one side of the top of the main body mechanism. The other side of the top of the main body mechanism is fixedly mounted with the driving mechanism for driving the device. The driven crushing mechanism for crushing the raw material is installed at the top end of the inner wall of the main body mechanism. The stirring mechanism for stirring the raw material is attached to the bottom end of the inner wall of the main body mechanism. USE - The device is useful for preparing graphene (claimed). ADVANTAGE - The device: reduces the particle diameter of the raw material reaction; facilitates the entry of the raw material; increases the reaction area of the raw material; enhances the reaction rate; and improves the efficiency. DESCRIPTION OF DRAWING(S) - The diagram shows a schematic representation of the device for preparing graphene.
