- Аннотация: 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.
