The article considers the calculation of a rotary apparatus with movable blades for the production of graphene-containing suspensions, which are used to modify structural and functional materials with improved performance characteristics. The rationale is given for the expediency of obtaining graphene plates by the method of shear exfoliation of graphite directly in liquids that are part of these materials. The kinetics of the exfoliation process in inorganic and organic liquids has been investigated, and according to the results of the analysis, dependences are proposed for calculating the main operating and geometric parameters of rotary apparatus with movable blades.
A method and device for obtaining graphene-containing suspensions by liquid-phase shear exfoliation of graphite in a continuous mode have been developed. The comparison of the intensities of the process of exfoliation of graphite in the periodic and continuous modes was carried out and it was found that the intensity
of the exfoliation process in the continuous mode is higher than in the periodic one.
The limiting concentration of graphene structures in a suspension is reached 1.5 times faster when using an apparatus operating in a continuous mode than in a periodic mode, and its numerical value is greater (by at least 25 %).
