  • Method and system for precision spheroidisation of graphite
    Patent number: 11000857
    Abstract: A system is disclosed. The system includes an impact processor comprising an inlet and an outlet, a secondary classifier comprising an inlet and an outlet, the secondary classifier being downstream of and coupled to the impact processor, a recirculation mixer valve downstream of and coupled to the outlet of the secondary classifier, and a recirculation line coupling the outlet of the first secondary classifier to the inlet of the impact processor.

  • Purification process modeled for shape modified natural graphite particles
    Patent number: 10710882
    Abstract: Embodiments of the invention are directed to systems and methods for purifying graphite particles. Graphite flakes can be milled, and then separated into groups with different nominal sizes. The different groups of particles are purified according to optimized purification processes. Groups of purified particles with narrow size distributions are created using embodiments of the invention.
