Expansion of technological capabilities of vibration dispergators by equipment by their resonant vibrodrives

The problems arising by production of powders and fibers of granular-like chips from the viscous and fragile materials applied in various branches are considered. Feature of this problem consists in providing tough requirements to the sizes, deviations of the sizes and a form of disperse particles which can't be received when using traditional, outdated, technologies of processing of materials. Application of a new way of the initiation of resonant fluctuations in vibrodrives providing improvement of technological parameters of vibration machines-dispergators is proved. Novelty of a method consists in receiving the synchronous oscillations in technological system and their maintenance at the given level, and also in a possibility of control of the form of the generated oscillations. The offered method allows to increase the power, universality and overall performance of vibrodrives, at the expense of a possibility of control of the form of a path of oscillations of a working organ and simultaneous synchronization high-frequency and low frequency component oscillations. It is shown that the functional capabilities of vibrodrives can be expanded due to excitation of mechanical oscillations on resonance frequencies. For more complete and evident idea of process of initiation of resonant fluctuations means of SUSU supercomputer resources have executed calculations of frequency characteristics of fluctuations of rotors of the vibrodrive. For comparing of paths and forms of oscillations, vectorial charts of movement of radius vectors of summary amplitudes of oscillations in case of nonsynchronous and synchronous operation modes were provided. As a result of calculations three forms of own resonant fluctuations of each of vibrodrive rotors have been revealed. The system of automated management allowing to make collecting at vibrodrives of parametrical information, its automatic processing and adjustment of steady synchronous work by means of electric feedback has been developed for monitoring and maintenance of the required technological parameters of the vibrodrive.
