ResumoCrystallization kinetics experiment of calcium sulfate dehydrates, which is prepared by bittern under 20°C and 120r/min conditions, is carried out. According to the results of the experimental data, nucleation density n 0 of gypsum crystals is proportional to the residence time, and the rate of crystal growth line G is inversely proportional to the residence time. Meanwhile, the crystallization kinetics formula is derived to be: B 0 = 5.78×10 2 G 0.87 .
