The article presents the results of the refinement of the mathematical model of the process of liquid-phase shear exfoliation of graphite and experiments on the production of graphene concentrates based on synthetic oils in a rod drum mill. The model parameters were identified and its adequacy to the real process was experimentally confirmed. It is given the dependence of the coefficient of light absorption, which characterizes the average integral value of graphene layers in suspension particles and their concentration on the processing time.
