Description of the Process of Vibrational Mixing of Elastoviscoplastic Multicomponent Mixtures

Resumo

Criterial equations characterizing the effect of vibration on mixing of multicomponent mixtures were derived based on similarity theory and dimensional analysis with respect to two key rheological properties, namely, specific resistance to mixing p and dynamic viscosity μ of an elastoviscoplastic multicomponent mixture. The derived equations can be used to evaluate the nature of breakdown of the structure of the multicomponent mixture in the housing of rotating-vibrating or in the drum of vibrating gravity mixers and to select the appropriate parameters of the structural elements of the mixers depending upon the boundary conditions of the studied process. These criterial equations were used to derive more precise equations of separation degree with respect to the key rheological parameters that enable one to evaluate and predict the quality of the multicomponent mixtures obtained in the vibrational mixing process.
