Abstract
The concentration of particular size throughout the bed was experimentally studied on a fluidized bed of glass beads with an acrylic column of 50 mm diameter and 1000 mm height, and analyzed by the application of the axial diffusion model for particles of two sizes.
From the experimental results, it was found that the axial distribution of void fraction might become that calculated by the assumption of perfect classification for the range of present conditions. The estimation method of size distribution of crystals from a classified-bed crystallizer is proposed on the axial diffusion model, using the relation between crystal size and bed height under the assumption of perfect classification in the author''s previous report. It is shown that the size distribution of sodium chlorate crystals from a test plant and sodium sulfate from pilot and industrial plants of this type agree with the calculated results from the model.
