Moving properties of a fluidized needle crystal of calcium sulfate were studied. It was shown that the terminal velocity of a needle crystal was dominantly affected by the diameter of the needle in the range where the crystal's length-to-diameter ratio was 20 to 100 and Reynolds number was 0.4 to 2.2. The correlation among terminal velocity of a needle crystal, superficial velocity and void fraction was obtained.<BR>A new estimation method for the average particle diameter of needle crystals in a fluidized bed crystallizer is proposed from observation of the height of a fluidized bed as an application of the correlation obtained in this study, and crystal growth rate was calculated from the difference of mean particle diameter in the growing period. This crystal growth rate was correlated against 0.7 power of supersaturation.
