Electrolysis of anhydrous magnesium chloride is one of the main ways to prepare metallic magnesium.In the process of preparing metallic mag-nesium by electrolysis,the preparation of anhydrous magnesium chloride is particularly important.Anhydrous magnesium chloride is generally obtained through segmented dehydration.This study investigates the formation process of magnesium chloride particles during the centrifugal granulation process of magnesium chloride solution.The factors affecting particle formation,particle size and particle motion trajectory were studied using simulation and experi-mental methods;The displacement equations and two-dimensional motion trajectories of particles in the horizontal and vertical directions over time were calculated;Analyzed the effects of initial velocity,particle size and air density on the motion trajectory of magnesium chloride particles.The larger the ini-tial velocity,the greater the horizontal displacement of particles,and the larger the umbrella diameter of granulation;The larger the particle size,the grea-ter the horizontal displacement,and the larger the particle motion diameter;The lower the air density,the smaller the resistance,the greater the horizontal displacement of particles,and the larger the diameter of the granulation umbrella.
