▎ 摘　　要

NOVELTY - The system comprises a grinding device (1), a conveying device (2) and a drying device. The grinding device comprises a grinding case (11). The top of grinding case is provided with a feeding hopper. The grinding case is provided with a dispersing cavity and a grinding cavity. The dispersing cavity is located at the upper end of the inner cavity of grinding case. The dispersing cavity is provided with a dispersing mechanism. The lower end of dispersing cavity is provided with a connecting channel. A bottom of a drying cylinder (31) is connected with a collecting box through pipeline, where upper end of drying cylinder is set with a guide plate. A water tank (36) is set on one side of drying cylinder and is provided with a water pump (37). The output end of water pump is connected with a water conveying pipe, where other end pipe is connected with the top of drying cylinder and the inner wall of drying cylinder is connected with an atomizing nozzle. USE - Graphene powder preparation system for preparing carbon nano-tube slurry. ADVANTAGE - The time of drying the graphene powder is increased under the action of the guide plate. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the graphene powder preparation system.
