| Abstract: | Effects of drum speed, particle diameter, particle density, shape factor and total mass of particles in bed on the pressure drop across fluidized bed and minimum fluidized velocity are studied respectively. Modified formula for calculation of pressure drop across fluidized bed and relation of dimensionless group of minimum fluidized velocity are proposed. This study lays the foundation for studying performance of the dryer in advance. |
