Показано, что увеличение температуры прессования со 120 до 142 °С существенно повышает интенсивность процессов рекристализации частиц и образования расплава в местах контакта частиц в зоне пластической деформации, что обеспечивает большую прочность межчастичных контактных связей за счет образования дополнительных связей кристализационного типа. При этом фракционный состав гранулята практически не изменяется. Выявлено только незначительное снижение динамической прочности гранулята в результате небольшого увеличения количества трещин в гранулах, что не является критичным для получения качественного готового продукта. В целом увеличение температуры прессования галургического мелкозернистого хлористого калия до 140–145 °С позволяет без реконструкции существующих производственных линий повысить производительность грануляционных установок до 130 % при сохранении высоких прочностных и гранулометрических характеристик готовой продукции. При этом переход на более высокие температуры прессования требует решение проблемы интенсивного налипания соли на рабочих поверхностях валков валковых прессов на основе технической модернизации существующих установок прессования с учетом выработанных рекомендаций.</p></abstract><trans-abstract xml:lang="en"><p>The regularities of the influence of the pressing temperature in the roll compactors of halurgic fine-grained potassium chloride on the performance of the granulation process and the physical and mechanical properties of the granulate under the conditions of the Sylvinite Processing Plant of JSC “Belaruskali” are determined. It is shown that an increase in the pressing temperature from 120 °C to 142 °C significantly enhances the intensity of the processes of particles recrystallization and melt formation at the particles’ contact points in the zone of plastic deformation, which provides greater strength of interparticle contact bonds due to the formation of additional bonds of the crystallization type. At the same time, the particle size distribution of the granulate practically does not change. Only a slight decrease in the dynamic strength of the granulate was revealed as a result of a small increase in the number of cavities and cracks in the granules, which is not critical for obtaining a high-quality finished product. In general, an increase in the pressing temperature of halurgic fine-grained potassium chloride up to 140–145 °C enables to enhance the capacity of granulation plants up to 130 % without reconstruction of existing production lines while maintaining the high strength and granulometric characteristics of finished products. At the same time, the switch to higher pressing temperatures requires solving the problem of intensive salt caking on the working surfaces of the rolls of roll compactors based on the technical modernization of the existing compacting plants, taking into account the recommendations developed.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>валковый пресс</kwd><kwd>хлористый калий</kwd><kwd>гранулят</kwd><kwd>давление</kwd><kwd>температура прессования</kwd></kwd-group><kwd-group xml:lang="en"><kwd>roll compactor</kwd><kwd>potassium chloride</kwd><kwd>granulate</kwd><kwd>pressure</kwd><kwd>pressing temperature</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">Belov V.
