The development of analytical methods for predicting the strength characteristics of pellets produced by the compaction of fine-grained materials remains a significant and relevant area. To advance this area, the mechanisms of phase interactions in bulk media were analyzed. The analysis was then used to develop local models of adhesion processes for two basic particle interaction schemes: ‘particle + particle’ and ‘particle + liquid phase + particle’. For each local model, the types, nature, and combination of adhesion processes that occurred simultaneously were theoretically established, and the factors and indicators that determined the occurrence and intensity of adhesive bonding were justified. The experimental studies conducted in the laboratory premises of the Nekrasov Iron and Steel Institute of the National Academy of Sciences of Ukraine were analyzed to evaluate the nature and extent of influence exerted by the selected factors, determining the adhesion processes, on changes in the strength characteristics of compacts. Considering the results obtained and the analytical dependences established for the ‘particle + particle’ interaction scheme, a method for predicting the strength characteristics of pellets produced from fine-grained materials with zero moisture was developed. This paper justifies the methodological conditions for experiments intended to create strong bonds within the compacts under the ‘particle + liquid phase + particle’ interaction scheme, taking into account the mechanical, physical, and physicochemical interaction processes between individual particles of the pelletized material and between the charge components (liquid phase). A generalized analysis of the experimental findings was carried out to estimate the range of potential adhesion processes inherent in the ‘particle + liquid phase + particle’ interaction scheme, identify their manifestation, study the nature of their interaction, and evaluate the effect of introducing the liquid phase into the pelletized charge, considering the applied compaction pressures. The collected array of experimental data will enable a detailed cross-correlation analysis to determine the influence of various factors on the adhesion processes and the formation of strong bonds within the compacts. The analysis will also help establish the dependence of strength characteristics of compacts on integral indicators contributing to the formation of adhesive bonds and describe the dependence by analytical methods. The results will be used to develop a method to determine the moisture content in the charge required to produce compacts with maximum strength from materials that belong to the first of the four groups of systematization. The classification of materials into specific groups of systematization is determined by their pycnometric density.

用于预测由细粒材料压实产生的颗粒的强度特性的分析方法的开发仍然是一个重要且相关的领域。为了推进这一领域的发展，分析了体介质中相相互作用的机制。然后使用该分析为两种基本颗粒相互作用方案开发粘附过程的局部模型：“颗粒+颗粒”和“颗粒+液相+颗粒”。对于每个局部模型，从理论上建立了同时发生的粘合过程的类型、性质和组合，并论证了决定粘合发生和强度的因素和指标。对在乌克兰国家科学院涅克拉索夫钢铁研究所实验室进行的实验研究进行了分析，以评估所选因素对强度特性变化的影响性质和程度，确定粘合过程的契约。考虑到所获得的结果以及为“颗粒+颗粒”相互作用方案建立的分析依赖性，开发了一种预测由零水分细粒材料生产的颗粒的强度特性的方法。本文论证了旨在在“颗粒+液相+颗粒”相互作用方案下在压坯内形成牢固结合的实验的方法条件，考虑到造粒材料的各个颗粒之间以及颗粒之间的机械、物理和物理化学相互作用过程。电荷成分（液相）。对实验结果进行了概括分析，以估计“颗粒+液相+颗粒”相互作用方案中固有的潜在粘附过程的范围，识别它们的表现，研究它们相互作用的性质，并评估引入考虑到所施加的压实压力，将液相引入颗粒状装料中。收集到的一系列实验数据将能够进行详细的互相关分析，以确定各种因素对粘附过程和压坯内强粘结形成的影响。该分析还将有助于确定压坯强度特性对有助于形成粘合键的整体指标的依赖性，并通过分析方法描述这种依赖性。结果将用于开发一种方法，以确定用属于四组系统化中第一组的材料生产具有最大强度的压块所需的装料中的水分含量。将材料分类为特定的系统化组是由其比重瓶密度决定的。
