NOVELTY - A graphene production technique comprises taking ethanol, cyclopentadiene, trivalent iron salt and additive, stirring to obtain stripping solution, mixing with graphite flake, feeding into abrasive peeling machine, processing, standing to obtain primary product, centrifuging, taking supernatant, filtering, washing, freeze drying. The grinding machine comprises machine frame, control module, grinding module, blocking plate. The control module comprises telescopic rod, first motor, first gear, first and second elliptical gear, first and second rod, and first and second slide block (27,29). The grinding module comprises second motor, third motor, first and second fixing plate, and upper and lower millstone with feeding port. USE - Graphene production technique. ADVANTAGE - The method improves the efficiency and quality of the graphene grinding.
