▎ 摘　　要

NOVELTY - Device comprises a reaction chamber (2), a grinding tank (1) arranged at middle bottom of the reaction chamber connected to a raw material pipe (3), a gas inlet (15) arranged in the lower right corner of the reaction chamber, and a vacuum pump installed in the upper left corner of the reaction chamber. A motor (7) is installed on the top of the reaction chamber, where the motor is connected below the rotating rod (11). A grinding sphere (12) is disposed on the bottom of the rotating rod, where a gas outlet (10) is provided in the upper right corner of the reaction chamber. USE - Device for preparing graphene composite material. ADVANTAGE - The device provides better yield and higher product quality in a reduced cost, and is suitable for industrial production. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the device for preparing graphene composite material.
