Narrow Results

We investigate on dynamic properties of particles in fluidized bed for separation with considering on gravity force, flotation, drag force and additional mass force for particles. The kinetic equations of particles in fluidized beds are built in detail based on the dynamic equations. It is found that the velocity of falling in fluidized bed can be described by hyperbolic tangent function and the distance of falling is described by the natural logarithm function. The results show that the particle size and the rate of density between the particle and the fluidized bed are the best of all basic factors in the course of efficiency particle separations. The theoretical study is pertinent to the application of mineral processing and efficient separations for fluidized bed.
