▎ 摘　　要

NOVELTY - The device has a processing barrel (1) whose top of the inner wall is connected with a circular slide rail (2). The top of the processing barrel is connected with a first motor box (3). The inside of the first motor box is connected with a first motor (4). The output shaft of the first motor is connected with a drive shaft (5). The bottom end of the drive shaft penetrates the processing barrel and the circular slide rail and extends below the circular slide rail. A drive gear (6) is connected to the surface of the drive shaft and located below the circular slide rail. The surface of the grinding roller is in contact with the inner wall of the primary sieve barrel. The bottom of the inner wall of the first-level sieve barrel is located below the drive shaft. A fixed gear is connected to the surface of the mounting sleeve and located between the bottoms of the two transmission gears meshing with the fixed gears. The top sides of the processing barrel are provided with a feeding hopper. USE - Multi-stage grinding and stirring device for graphene slurry. ADVANTAGE - The production process of batch screening is reduced and the processing efficiency of graphene slurry is improved. The multi-stage grinding ensures the fineness of raw materials and improves the production quality of graphene slurry. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic structural diagram of the multi-stage grinding and stirring device for graphene slurry.
