NOVELTY - Producing graphene involves mixing graphite and solvent, performing at least one low-speed stirring treatment or/and low-speed shearing treatment to obtain a graphite dispersion, preliminary stripping graphite dispersion, subjecting to at least one sanding treatment to obtain a preliminary stripped graphene dispersion. The graphene dispersion initially stripped is subjected to at least high pressure homogenization treatment or/and sonication is performed to obtain a single layer or a small layer of graphene dispersion. The single-layer or small-layer graphene dispersion is subjected to filtration, centrifugation, washed, and dried to obtain final product. USE - Method for producing graphene. ADVANTAGE - The method enables to produce graphene which has high purity, thin thickness,large specific surface area, low resistivity, and has low metal impurity content. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a device for continuously producing graphene, which comprises a first dispersing device, sanding device, high pressure homogenizing device, a first overrunning line in parallel with the high pressure homogenizing device, and an ultrasonic processing device a second overrunning line and a liquid storage device in parallel with the ultrasonic processing device, where outlet end of the first dispersing device is respectively connected to the inlet ends of the high pressure homogenizing device, the sanding device and the liquid storage device, outlet end of the sanding device is respectively connected to an inlet end of the first dispersion device and an inlet end of the liquid storage device, outlet end of the high pressure homogenizing device is connected to an inlet end of the ultrasonic processing device, outlet end of the sonication device is connected to the inlet end of the first dispersion device or to the inlet end of the liquid storage device.
