The study involves an analysis of diverse technologies for recycling complex chemical power sources, including processes such as unsealing, crushing, grinding, leaching with sedimentation, and filtration. The recycling technology for spent lithium-cobalt power sources, developed at the National Research Center “Kurchatov Institute,” is explored. This technology involves discharging lithium-cobalt power sources in a NaCl solution, unsealing in a shredder under an inert atmosphere, grinding in a rotary cutting mill equipped with a cyclone, and further grinding in a disintegrator to produce mechanically activated powders. The article provides data on the elemental composition and product yield following discharge, leaching, and precipitation. In addition, studies were carried out on pelletizing the resulting powders by pressing and rolling in a rotary granulator with a flat die. To enhance efficiency, the characteristics of channels with variable cross-sections were examined, and a physical and mathematical model for constructing force diagrams within the die channels was developed. Force distribution diagrams along the length of the channel were obtained for four types of powders, enabling the prediction of the behavior of powders with different morphologies during their rolling on a rotary granulator with a flat die.

该研究涉及对复杂化学能源回收利用的多种技术的分析，包括开封、破碎、研磨、沉淀浸出和过滤等过程。国家研究中心“库尔恰托夫研究所”开发了废锂钴电源的回收技术。该技术包括在氯化钠溶液中放电锂钴电源​​，在惰性气氛下在粉碎机中开封，在配备旋风分离器的旋转切割磨机中研磨，并在粉碎机中进一步研磨以生产机械活化的粉末。该文章提供了排放、浸出和沉淀后的元素组成和产品产量的数据。此外，还对通过在带有平模的旋转造粒机中压制和滚动而将所得粉末造粒进行了研究。为了提高效率，研究了可变横截面通道的特性，并开发了用于构建模具通道内力图的物理和数学模型。获得了四种粉末沿通道长度的力分布图，从而能够预测不同形态的粉末在带有平模的旋转造粒机上滚动期间的行为。
