NOVELTY - The device has a first circular baffle (2) located at a top part of a reaction chamber (1). The first circular baffle and the reaction chamber are connected with an unloading material pipe (3). A top part of the first circular baffle is fixedly connected with a feeding hopper (10). The reaction chamber is fixedly mounted with a mounting frame that is fixedly installed with a motor. An end of the motor is fixedly connected with a rotating shaft. An end of the rotating shaft is fixedly connected with a metering cylinder (6). An outer side of the metering cylinder is connected with the second circular baffle (5). The first circular baffle is sleeved in an outer side of the second circular baffle. USE - Metering rotary extruding device for preparing modified graphene powder. ADVANTAGE - The device has simple structure, and is convenient and practical, and can perform function of metering and conveying the graphene powder accurately. DESCRIPTION OF DRAWING(S) - The drawing shows a front view of a metering rotary extruding device. Reaction chamber (1) Circular baffles (2,5) Unloading material pipe (3) Metering cylinder (6) Feeding hopper (10)
