Abstract
Particle sizes and their distribution in a fluidized crystallizer can be determined by measuring the superficial velocity and pressure drops across the beds of various heights in fluidized beds.
The growth behavior of sodium chloride crystals in a fluidized crystallizer was investigated from crystal size distributions in a three-hour cystallization. The Ergun equation for pressure drop of packed beds in the transition flow region applied to the crystal size distributions was in good agreement with the size distributions obtained by a microscope method.
