Experimental investigations have been carried out for spherical and non‐spherical particles using beds comprised of single‐sized particles and mixtures in the size and particle density ranges of 439 to 1524 μm and 1303 to 4948 kg/m 3 , respectively. Five conical fluidizers with varying apex angles of 8.86, 14.77, 19.60, 32.0 and 43.2 degrees were used. Experimental values of minimum velocity and bed pressure drop with air as the fluidizing medium have been compared with their respective values obtained from different models available in the literature. Deviations for each chosen model have been presented.
