При исследовании влияния того или иного фактора на эффективность самосортирования эксперименты проводили с одной и той же зерновой смесьюна рабочих поверхностях ограниченных с четырех сторон стенками при горизонтальных гармонических колебаниях горизонтальных рабочих поверхностей. В качестве модельной частицы была использована наиболее часто встречающаяся легкая примесь в зерне пшеницы – соломинка.Эксперименты посвящены определению времени всплывания легкой частицы в слое зерна пшеницы. Проведены эксперименты на рабочей поверхности с рифлями, образующими зигзагообразные каналы, рифлями переменной высоты,с расположением рифлей перпендикулярно направлению колебаний рабочего органа и с расположением рифлей под углом к направлению колебаний.В экспериментах варьировали толщину слоя зернового потока над рифлями и положение легкой частицы в слое относительно опорной поверхности, так чтобы можно было определять время всплывания легкой частицы через слой одной и той же толщины, но расположенный на различном расстоянии от рифлей опорной поверхности. Это позволило исключить влияние толщины слоя на время (скорость) всплывания легкой частицы и оценить влияние на интенсивность самосортирования (время всплывания) только рифлей опорной поверхности.Экспериментально доказано, что повышение эффективности процесса самосортирования на рабочей поверхности может быть обеспечено путем установки рифлей перпендикулярно направлению колебаний.</p></abstract><trans-abstract xml:lang="en"><p>The article is devoted to the substantiation of the creation of new bearing surfaces of the working bodies of vibration separating machines, the use of which contributes to an increase in the intensity of one of the stages of the separation processes - self-sorting. When studying the influence of one or another factor on the efficiency of self-sorting, experiments were carried out with the same grain mixture on the working surfaces bounded on four sides by the walls with horizontal harmonic oscillations of the horizontal working surfaces. The most common light particle was used as a model particle. an impurity in the wheat grain is a straw. Experiments are devoted to determining the time of the emergence of a light particle in a layer of wheat grain. Experiments were carried out on the working surface with grooves forming zigzag channels, grooves of variable height, with the arrangement of the flute perpendicular to the direction of oscillation of the working member and with the arrangement of the flute at an angle to the direction of oscillation. In the experiments, the thickness of the grain flow layer above the grooves and the position of the light particle in the layer relative to the supporting surface were varied, so that the time when the light particle emerges through the layer of the same thickness but located at different distances from the flute of the supporting surface. This made it possible to eliminate the influence of the layer thickness on the time (speed) of the ascent of the light particle and to estimate the effect on the self-sorting intensity (the ascent time) only on the flute of the support surface. It has been experimentally proved that an increase in the efficiency of the self-sorting process on the working surface can be achieved by installing a flute perpendicular to the direction of oscillation.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>опорные поверхности</kwd><kwd>сепарирующие машины</kwd></kwd-group><kwd-group xml:lang="en"><kwd>bearing surfaces</kwd><kwd>separating machines</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Гортинский В.В., Демский А.Б., Борискин М.А.
