Смешение сухих компонентов в смесительных аппаратах является одним из важнейших этапов любого технологического процесса при изготовлении композиционного материала. К настоящему времени в различных технологиях используется самое разнообразное смесительное оборудование, которое характеризуется различными принципами смешения и конструктивными решениями. Особый интерес для приготовления качественных и однородных смесей теплоизоляционного назначения представляет пневматический смеситель со спиральной энергонесущей трубкой. В статье приведены результаты исследований с использованием метода математического планирования полнофакторного эксперимента ПФЭЦКРП24, позволяющего наиболее адекватно оценить происходящие процессы при минимизации систематических ошибок.Материалы и методы. В работе в качестве сырьевых материалов для проведения испытаний использовали портландцемент ЦЕМ 0 42,5Н ГОСТ 31108–2020 с удельной поверхностью 308 м2/кг, песок Вольского месторождения. В качестве легкого наполнителя использовали вспученный вермикулит, полученный в результате термообработки природного вермикулита при температуре около 700 °С.Результаты. Теплоизоляционные смеси, приготовленные в пневматическом смесителе со спиральной энергонесущей трубкой, обеспечивают получение теплоизоляционных растворов со стабильными показателями по плотности 1420 кг/м3, имеющие достаточные прочностные показатели при сжатии 3,3 МПа, гарантируют высокие теплозащитные свойства в строительных конструкциях.Заключение. Разработанная конструкция и проведенные исследования позволили установить высокую эффективность предлагаемого смесителя, обеспечивающего равномерное распределение смешиваемых частиц, высокую гомогенизацию и создание условий для ускорения физико-химических взаимодействий в создаваемой смеси при последующем затворении приготовленной смеси водой и формирование требуемой внутренней структуры создаваемых композитов.</p></abstract><trans-abstract xml:lang="en"><p>Introduction. Mixing of dry components in mixers is one of the most important stages of any technological process in the manufacture of a composite material. To date, various technologies use a wide variety of mixing equipment, which is characterized by different principles of mixing and design solutions. Of particular interest for the preparation of high-quality and homogeneous mixtures for heat-insulating purposes is a pneumatic mixer with a spiral energycarrying tube. The article presents the results of studies using the method of mathematical planning of the fullfactor ПФЭЦКРП24 experiment, which makes it possible to most adequately assess the ongoing processes while minimizing systematic errors.Materials and methods. In the work, ЦЕМ 0 42,5Н ГОСТ 31108–2020 Portland cement with a specific surface area of 308 m2 / kg, sand of the Volsky deposit were used as raw materials for testing. Expanded vermiculite obtained as a result of heat treatment of natural vermiculite at a temperature of about 700°C was used as a light filler.Results. Heat-insulating mixtures prepared in a pneumatic mixer with a spiral energy-carrying tube ensure the production of heat-insulating mortars with stable density values of 1420 kg/m3, having sufficient compressive strength of 3.3 MPa, and guarantee high heat-shielding properties in building structures.Conclusion. The developed design and the conducted studies made it possible to establish the high efficiency of the proposed mixer, which provides a uniform distribution of the particles to be mixed, high homogenization and the creation of conditions for accelerating the physicochemical interactions in the created mixture with subsequent mixing of the prepared mixture with water and the formation of the required internal structure of the created composites.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>смешение</kwd><kwd>вяжущая композиция</kwd><kwd>вермикулит</kwd><kwd>портландцемент</kwd><kwd>пневматический смеситель со спиральной энергонесущей трубкой</kwd></kwd-group><kwd-group xml:lang="en"><kwd>mixing</kwd><kwd>binder composition</kwd><kwd>vermiculite</kwd><kwd>Portland cement</kwd><kwd>pneumatic mixer with a spiral energycarrying tube</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено за счет гранта РНФ № 22-19-20115, https://rscf.ru/project/22-19-20115/ и Правительства Белгородской области, Соглашение №3 от 24.03.2022.</funding-statement><funding-statement xml:lang="en">The study was supported by the RSF grant No. 22-19-20115, https://rscf.ru/project/22-19-20115/ and the Government of the Belgorod Region, Agreement No. 3 from 03/24/2022.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Ясинская Е.
