【 摘 要 】

To solve the problem of obtaining superfine materials, a mathematical model of materials dispersion is proposed. The model uses the Focker-Planck equation to determine the probability density. The physical density of the probability density is interpreted as a differential characteristic of the composition of the ground material. The closure is performed using the equations of material balance and limitations that ensure the performance of low-tonnage technological complexes. Criteria for the controllability of the grinding process are proposed. These criteria take into account the random nature of the processes and the existing disturbances in the chamber of the vortex-acoustic disperser. In this case, the vortex-acoustic disperser in the working range of changing its parameters is considered as a complex physico-mechanical system. The developed mathematical model makes it possible to study the laws of the grinding process in a vortex-acoustic disperser. The model also makes it possible to find the optimal design and operational parameters of the disperser.
