Одним из основных методов обогащения, применяемых в технологическом процессе переработки различных руд, считается пенная флотация. Приведено краткое описание этого процесса, проанализированы различные конструкции флотационных машин. Работа посвящена модернизации аэрационного узла флотационных машин конструкции «РИФ». Отмечено, что при проектировании таких машин эффективно используется модульный принцип компоновки агрегатов, который позволяет модернизировать отдельные узлы, повышая эффективность работы машины в целом. Основной деталью этого узла является самая сложная и быстро изнашиваемая деталь – импеллер. Проанализированы различные конструкции импеллеров и технологии их изготовления. Отмечено, что в существующих конструкциях флотационных машин импеллеры изготавливают из стали. Предложено заменить этот материал на полиуретан, который получил широкое распространение как конструкционный материал в связи с появлением аддитивных технологий при производстве различных деталей. Это материал имеет относительно невысокую стоимость и обладает повышенной сопротивляемостью износу. Сформулированы основные требования к важнейшим операциям технологического процесса изготовления импеллера. Для этого в системе трехмерного автоматизированного проектирования Компас разработана 3D-модель модернизированной конструкции импеллера. Предложена аддитивная технология послойного изготовления импеллера на 3D-принтере с использованием программы-слайсера Ultimaker Cura. Для изготовления импеллера предложенной конструкции из полиуретана разработана технология производства методом послойного наплавления Fused Deposition Modeling (FDM).</p></abstract><trans-abstract xml:lang="en"><p>The constant increase in the consumption of ferrous, non-ferrous, precious and rare metals in the national economy requires an increase in the efficiency of minerals mining and processing. One of the main methods of enrichment used in the technological process of processing various ores is foam flotation. The authors provide a brief description of this process and analysis of various designs of flotation machines. The article is devoted to the modernization of the aeration unit of flotation machines with “RIF” design. It is noted that the design of such machines effectively uses the modular principle of assembly aggregates, which allows you to upgrade individual unit, increasing the efficiency of the machine as a whole. The main part of this unit is an impeller – the most complex and fast – wearing part. The paper analyzes various designs of impellers and their manufacturing technologies. It is noted that in the existing designs of flotation machines, the impellers are made of steel. It is proposed to replace this material with polyurethane, which has become widely used as a structural material due to the emergence of additive technologies in the production of various parts. This material has a relatively low cost and has an increased resistance to wear. The article formulates the main requirements for the most important operations of the technological process of impeller manufacturing. For this purpose, a 3D model of the upgraded impeller design was developed in the SolidWorks 3D computer-aided design system. The authors propose an additive technology for layer-by-layer production of an impeller on a 3D printer using the Ultimaker Cura slicer program. For the manufacture of the proposed design of the impeller made of polyurethane, the production technology was developed by the method of layer-by-layer deposition method of Fused Deposition Modeling (FDM).</p></trans-abstract><kwd-group xml:lang="ru"><kwd>флотационная машина</kwd><kwd>аэрационный узел</kwd><kwd>импеллер</kwd><kwd>компьютерное моделирование</kwd><kwd>слайсер</kwd><kwd>управляющая программа</kwd><kwd>ад- дитивные технологии</kwd></kwd-group><kwd-group xml:lang="en"><kwd>flotation machine</kwd><kwd>aeration unit</kwd><kwd>impeller</kwd><kwd>computer simulation</kwd><kwd>slicer</kwd><kwd>control program</kwd><kwd>additive technology</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">Бухоров Ш.Б., Қодиров Х.И.
