FIELD: mining engineering.
SUBSTANCE: method includes velocity delivery of a jet to a hydrodynamic generator, treatment of the hydraulic mixture under the conditions of active hydrodynamic effects by means of the influence of a body placed therein and successively installed stationary elements, including plate cavitation elements, with provision of deep disintegration of the mineral component of the hydraulic mixture to micro-level by converting the kinetic energy of liquid flow into the energy of acoustic vibrations in the hydrodynamic generator. In order to create stability conditions of the system, taking into account electrostatic interaction of the diffusion layers of ions of mineral component particles of the hydraulic mixture, the velocity jet is fed to a spider with cassettes rigidly fixed along the axis of the hydrodynamic generator, through flow stabiliser with splitters for subsequent distribution of flow in gaps along flat surfaces of cassettes installed on two sides of the spider guides with gaps in parallel relative to each other, with a shift in vertical direction due to reduction of flat surfaces area of mineral component, and a shift in horizontal direction-from the spider connection center to the body walls and fixed in the grooves of angular and radius inserts. The additional jet separation with the intensification of the cavitation-acoustic effect on the hydraulic mixture mineral component to obtain given average value of the volumetric density of the hydrodynamic effect on the microparticles is carried out at the outlet by means of accumulation of the flow in confuser zone with stationary cavitators longitudinally installed along the flow direction.
EFFECT: increased efficiency of microdisintegration process.
