FIELD: mining.
SUBSTANCE: invention relates to the mining industry and can be used in the development of natural and man-made high-clay placer mineral deposits with a high content of small-sized and fine fractions of valuable components. Method for activating the micro-disintegration of the polymineral component of a hydraulic mixture includes a high-speed supply of a jet to a hydrodynamic generator; processing of the hydraulic mixture in conditions of active hydrodynamic effects by means of the influence of the stationary cavitation elements placed inside the body and installed in series, ensuring deep disintegration of the mineral component of the hydraulic mixture to the microlevel by converting the kinetic energy of the liquid flow into the acoustic oscillation energy in the hydrodynamic generator. When the high-speed jet is emitted onto a reflective surface with radial roundings, rigidly fixed on the fairing by means of a connecting element, turbulent vortices are modelled, with the flow separated towards the fairing with slot-shaped holes, linked with the crosspiece and the support beams, and simultaneously towards the gap formed with the walls of the body. In order to enhance the hydrodynamic effect on the polymineral component of the hydraulic mixture and reach the set average value of the volumetric density of hydrodynamic disturbance to ensure the pressure gradient exceeding the strength limit of the microparticles, the flow of the hydraulic mixture is supplied gradually through the slot-shaped holes onto the smooth inclined surfaces of conical elements installed with a reverse cone to increase the pressure during the supply of hydraulic mixture through the holes at all levels, and then onto the flat surfaces installed in the central part of the turbulators. The turbulators are installed at different levels with a gap relative to the walls of the conical body; and the flow of the hydraulic mixture, directed by the smooth fairing surfaces towards the gap, reaches the flat surfaces made along the perimeter of the turbulators. The flow of the hydraulic mixture is supplied to the confuser and output along the flow guides to be further enriched by gravitational methods; wherein the stability and rigidity of the design of the body, the diffuser, the confuser, and all stationary cavitation elements of the hydrodynamic generator are provided by the support stability elements.
EFFECT: increase in the production and operation efficiency of the process of deep disintegration of the polymineral component of the hydraulic mixture.
