NOVELTY - The utility model claims a preparation system for mass production graphene powder, the system comprises an ultrasonic oxidation mechanism for preparing graphite oxide with a first viscosity; the ultrasonic oxidation mechanism comprises a discharge port formed at the lower part thereof; a water washing mechanism, for receiving the graphite oxide discharged from the discharge port under the action of gravity and diluting the graphite oxide to obtain the graphite oxide slurry with the second viscosity; The first viscosity is greater than the second viscosity. The invention claims a mass production graphene powder preparation system, which can effectively solve the problem that the oxidized graphite viscosity is difficult to transport in high production process. leaking the oxidized graphite from the oxidation mechanism; diluting in the water washing mechanism, centrifuging, washing, purifying, drying and crushing; it can solve the problem of difficult continuous production caused by viscous, low production efficiency, reaching the purpose of continuous production and mass production.
