This article substantiates a new concept of dimensional mechanical dispersion of viscous plastic materials in condensed media by cutting. It is about increasing geometric homogeneity and forming a required shape and size of dispersed particles by forcibly introducing a specified controlled vibration action into the area of material destruction. This approach will allow us to move from the traditional (chaotic) to the new highly organized and controlled process of destructing viscous condensed media of various structures. Achieved results make it possible to produce dispersed powder and fiber particles of required quality without changing the physicochemical characteristics. They will also contribute to the processes of developing vibration-assisted cutting technologies and designing high-technology energy efficient dispersing machines.
