The processes of agglomeration of dispersed materials, the relevance of their use in the utilization of man-made powdered materials. Shows the need for prehardening of the granulated charge when they are balling with balling. This is especially true for man-made materials with low bulk density, which is an obligatory stage for the formation of micro-granules, the subsequent growth and compaction of which occurs under the action of centrifugal forces. Analytical expressions for calculation of rotation frequency of the forming rolls providing necessary conditions for realization of processes of filtration of gaseous and liquid phases of a composite mix, and also for reception of microgranules of the set density at a vibro-roll method of preliminary compaction are presented. The obtained dependences are the basis for the development of a vibration-centrifugal granulator for the step-by-step process of forming technogenic dispersed materials with low bulk density.
