FIELD: concentration of mineral resources. SUBSTANCE: a radiator, generating plane travelling longitudinal waves, is placed in liquid medium. A non-periodical component is separated from them which acts on the particle in liquid with force:where- force of action of non-periodical component on particle, N; A - medium amplitude, kg/m; S - particle geometric dimension;- medium speed, m/s; γ - wave attenuation factor, m; l - shortest current distance between the source of disturbance and the particle distance, m. The radiator is positioned in such a manner so as to bring together the values of the field length and particle dimensions, i. e. at distance L from the particle, determined by relation. EFFECT: facilitated procedure. 2 dwg |
