Conversion air velocity at which reverse density segregation converts to normal density segregation in a vibrated fluidized bed of binary particulate mixtures
2022, Advanced Powder TechnologyCitation Excerpt :When binary mixtures of different-density particles of the same size are fluidized by airflow through the bottom, normal density segregation occurs; lighter particles move upward and the heavier ones move downward. The fundamentals of the segregation have been widely investigated, and the segregation has been applied to dry gravity separation of particulate mixtures [5–24]. The addition of vibration to the fluidized bed is a useful method to achieve good fluidization of fine cohesive particles [25–32].
