UDC 532.546

Based on the principle of hydrodynamic equivalence, a technique to calculate 
the velocity of complete fluidization of polydisperse granular materials 
of different densities with allowance for the transformation 
of their initial size distribution has been worked out.

Keywords: polydisperse fluidization bed, minimum of fluidization velocity, 
complete fluidization velocity, discrete size distribution of particles, 
continuous size distribution of particles, equivalent diameter of particles.
