Abstract: Mixing/Segregation of an iron-and-sand mixture was investigated in a 38 mm diameter moving fluidizedbed with feed into the middle of the bed and exit from both the top and the bottom.The distribution ofvolumetric concentration of iron beads,measured by means of a specially designed sampler,was used to expressthe degree of segregation of the particle mixture in the bed.The segregation index N,defined as the ratio betweenS and Z.X_v,decreases with increase in superficial gas velocity and solids flow rate,for any given solidsdensity ratio and particle size ratio.When a magnetic field was employed,particle segregation was noted toincrease with magnetic field strength.
