Abstract: For the sake of investigating hydromechanical behavior of particles in vibrated fluidized bed, this paper studies the effects of vibration intensity, height of bed and gas velocity on pressure drop through a model vibrated fluidized bed equipment with rubber particles as sample materials. The variations of minimum fluidization velocity along with height of bed and vibration intensity are also analyzed. A helpful conclusion is obtained by comparing experimental results of rubber particles to those of nylon-1010. The research work of hydromechanical behavior of rubber particles in vibrated fluidized bed can present reasonable advice on cryogenic heat transfer between low temperature gas flow and rubber particles in cryogenic comminution.
