It is known that nanodispersible powders are the condensed medium which at the same time have properties of liquid and solid bodies. And properties of such an environment strongly depend on particle size. In this work, the acoustic method of division of ultradispersible powders on the fluctuating plate is considered. The experimental data by the efficiency of the division of nanoparticles of dioxide of silicon are obtained. Based on a method of successive approximations of the Navier-Stokes equations for vorticity the equations and boundary conditions for the fluctuating plates taking into account amplitude to the second- order are received. Using the Mathematica system, analytical decisions are received and plots of vectors fields of speeds for a plate of the infinite length are constructed.
