В основе данного метода лежит ранее обнаруженный квазикапиллярный эффект, заключающийся в том, что если полый цилиндр (трубку) опустить в псевдоожиженный слой, то внутри цилиндра создаются условия для интенсивного пневмотранспорта твердой фазы, вследствие этого высота, на которую поднимается дисперсная среда внутри трубки, превышает высоту псевдоожиженного слоя. Отличительной особенностью метода является отсутствие загрязнения окружающей среды (слой, из которого удаляется мелкая фракция, является практически неподвижным), а также значительно меньшая энергоемкость, так как энергия не затрачивается на отвод и транспортировку мелких частиц, а расходуется только на минимальное ожижение удаляемой из слоя фракции.</p><p> </p></abstract><trans-abstract xml:lang="en"><p>The method of removal of fine fraction from a polydisperse granular layer is experimentally investigated in order to increase its uniformity on the sizes of particles. This method is based on the earlier found out unusual effect consist in moving down the cylinder (tube) in fluidization layer; then inside the cylinder, the conditions for intensive pneumotransport of a firm phase are created. Consequently, the height, on which the disperse environment inside a tube rises, exceeds height of fluidization layer. Distinguishing feature of this method is absence of environmental contamination (a layer where of the fine fraction leaves is slightly motionless), and also is far less power consumption as energy is not spent on removal and transportation of minor particles, energy is spent only on minimal fluidization removal from a layer of fraction.</p><p> </p></trans-abstract><kwd-group xml:lang="ru"><kwd>полидисперсный зернистый слой</kwd><kwd>твердые частицы</kwd><kwd>псевдоожижение</kwd><kwd>разделение на фракции</kwd><kwd>дисперсная среда</kwd><kwd>псевдоожиженный слой</kwd><kwd>пневмотранспорт</kwd><kwd>газораспределительное устройство</kwd><kwd>скорость псевдоожижения</kwd><kwd>зернистые материалы</kwd><kwd>пристенный слой</kwd></kwd-group><kwd-group xml:lang="en"><kwd>polydisperse granular layer</kwd><kwd>solid particles</kwd><kwd>fluidization</kwd><kwd>separation on fraction</kwd><kwd>dispersion medium</kwd><kwd>fluidized bed</kwd><kwd>pneumotransport</kwd><kwd>gas distribution</kwd><kwd>fluidization velocity</kwd><kwd>granular materials</kwd><kwd>boundary layer</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">Hemery, Y.
