To develop the concept of two - stage semi - fluidization on hydrodynamic characteristics viz. the bed pressure drop and formation of the top packed beds, investigation have been carried out in a two - stage semi - fluidized bed with regular and irregular particles. Perspex column of internal diameter 2.54 cm with a 30 test section cm has been used for two stage study with water as the fluidizing medium. Glass beads and dolomite particles (0.1504 cm) have been used as solid phase material. Experimental parameter studied includes superficial liquid flow rate with constant bed expansion ratio. Mathematical modeling has been done for the bed pressure drop and the top packed bed height for two - stage semi - fluidization. Individual stage behavior and comparison of results have been made between single and the two - stage semi - fluidized bed with fixed amount of tot al solids and total volume of test section
